Lightroom Classic: Very slow on High-end PC

Hi guys,

I'm little bit disappointed and frustrated so i would like to know if somebody have the same problem.

Last week I build new PC for my photo editing ( Lightroom and Photoshop ) and little video in the future ( Premiere pro ). Here is my computer :

Windows 10 Pro
Processor : I7 7700k Kaby Lake OC  4.8 GHZ + Noctua ND-H14
Motherboard : MSI Z270 Gaming Pro Carbon
Graphic Card : Nvidia Gigabyte G1 GTX 1060 6GB
Memory : 64G Corsair Vengeance LPX 2400 MHz ( 4 x 16GB )
Disk 1 ( Windows + programs + Cache ) : Samsung 960 M.2 NVMe 500 GB
Disk 2 ( Working files - Photo and video ) : Samsung 960 M.2 NVMe 500 GB
Disk 3,4,5 ( Backup ) : WD Black 4TB + WD RED 4TB + WD RED 3TB
Power : XFX 750 PRO
Wacom Intous Pro

Monitor 1 : Dell 2007WFP 21"
Monitor 2 : Benq BL3200 32"
Monitor 3 : Dell U2713HM 27"

I was trying to get everything right for fastest workflow in Lightroom and Photoshop. The Samsung 960 disks are one of the fastest on the market. One of the disk is just for Windows + Programs + Catalog + Cache and I have around 400G free space. The other is just for Working files ( photos and video ). 

Disk are working good and everything works fast EXCEPT Lightroom and i am getting desperate. 
1. Crop tool is choppy and slow ( little bit better when GPU acc. is turned off )
2. Switching between photos in Develope mod is very very slow ( 2-3 sec )
3. Radial filters are slow
4. Brushes are slow
5. Synchronizing is slow
The only thing that is ok is EXPORT and IMPORT of the photos.
Everything is so choppy and slow that is driving me crazy. I have newest drivers for everything  and I tried last 3 versions of Lightroom 6 and it's the same.

GPU option is turned on ( it's even slower with it ) , i have 250 GB free for Camera raw cache, I imported 1:1 previews + Smart previews.

When i work the processor and ram usage is around 30-50 %. I know that Lightroom is programmed for 10 years old computers and it's badly optimized but this is awful,

Does anybody have the same problems?

Thanks

If you are an existing Lr Classic CC customer, and would like to test out a developer preview build that we think fixes this performance issue. Please send me a note and I'll make sure that you are invited to the prerelease program. Thanks.

Simon, I would be honored to be a beta tester for LR pre releases. (especially for performance and GPU („blacking out in develop mode“) issues)

Sounds like an awesome build. But from the symptoms you described, I think you are encountering the pitfalls of being an early adopter. I don't think that the development cycle has caught up to the NVMe technology. This could be a host of issues from Bios Settings in the MSI board to a wonky driver to Windows 10 itself. Sorry that I'm not much direct help but I did some searching on the problem.

If you are able to use some Samsung software to monitor how the SSD performance is with Windows 10 that might direct you to a BIOS, MSI board compatibility, or a driver for Windows 10 potential resolution.

But Kudos on the specs, sounds like a great PC.

Hi David,

Thank you for the replay. Yes, there are always bugs and problems with new system and usually it takes few months for some bugs and problems to be fixed.

But there is no problem with the NVMe disks. Motherboard is new and compatible with new disks and they are working fine. Every other program and task is working well except lightroom ( develope module )

I have all the newest drivers and updates ...it's very frustrating.

Thanks once again,

Kind regards

You might try decreasing the amount of RAM you installed in your system.  I know it sounds counter-intuitive, but it's one of the lessons I learned on my last PC build.  Anything over 16GB of RAM is typically never used by the system for the tasks you described, and unless your doing some kind of CG editing for a major motion picture, I doubt you would get anywhere even close to 32GB of RAM used at one time during the life of the computer.  64GB is more than overkill and could be bogging things down a little.

Also, you may want to go into your BIOS settings and make sure your motherboard is setup for 2400 MHz on your RAM.  When I built mine, I read that most motherboards default to 1300 or 1600 MHz, and regardless of the stated speed of the RAM you installed, it won't function at that speed unless you manually go into your BIOS and set it up to do so.

Hi Ann,

I've added more RAM for video in the future. I had 16G of ram on my old computer and it was fine just like you've said. I've removed few hrs ago 2 sticks and i have 32G ram now, but it's the same. 

XMP in bios is turned on for the ram because i have Overclocked processor to 4.8GHZ and everything is set ok and working stable. It's even on lower voltage than "factory setup" without overclock.

Thanks!

If none of those screens are 4k/5k, you'll likely be happiest with GPU turned off on preferences. In Preferences > Performance, try checking the use smart previews for editing checkbox and see if that helps your loading time.

You mentioned that RAM is at 30-50%. That sounds too high for normal Lightroom use, considering the amount of RAM you have installed, so I'm wondering if something else is going on. How long has Lightroom been installed and running since the new build? I've seen some poor performance around sync particularly.

Hi Victoria,


32" and 27" monitors are 2560 x 1440

Sorry about the RAM, i've written  wrong. I removed 2 sticks and now i have 32G of RAM and memory is on 14 % usage...processor depending on the tasks.

I've noticed that the sliders are much faster and responsive when i am working on one monitor than on 2.

I switched from my old I7 4770K platform mainly because of the new Samsung m.2 disks and more PCEi lanes.  Lighroom 5 was pretty slow my older computer but this is even worse.  

I have the newes drivers and everything updated ( new drivers from Graphic card are few days old ). Windows updated...lightroom too..

Every other program works pretty good and fast.

I disabled the GPU performance  and that helped with the crop tool a little, but everything else awfully slow. The switching between modules is little bit slower, but i am fine with that, the problem is working in develope module :(

Switching between photos takes 2-3 sec....if you press something you have to wait for ligjtroom to respond or few seconds. For example i want to  apply the crop or gradient on my photo, when i press ENTER i have to wait for few seconds and then wait for few seconds to get on the new photo.

Applying presets or sync is painfully slow....and i only have around 100 photos in Catalog. The processor is working maybe 15%-30% on those tasks and Ram usage is even lower....

That is why i don't get how some people have fast working lightroom or when i am watching Tutorials on the net it seams that the lightroom is working much faster at somebody's computer.

Thanks for the replay !

Kind regards

This is probably a silly thought, but your calibration profiles - Matrix or LUT? LUT profiles have been suspects in the past.

These performance issues you're seeing - with the smart preview checkbox enabled or not (and smart previews built, of course)? 

You could also test whether you see the same issues working with a much smaller LR window.

You might find it useful to run through the checklist in the back of my (free) performance eBook, just to double check there's not a helpful setting you've missed. https://www.lightroomqueen.com/performance 

Oh, and for good measure, I should just double check that you're running 2015.8, not an earlier build. (Under Help menu > System Info)

Hmm...not sure about calibration profiles...how can I check that?

I've calibrated my monitors with Colormunky Display ...icc profiles for every monitor.

Yes i am running 2015.8 Tail version of the lightroom

Set the Colormunki software Preferences as shown below. Set #5 to match the display type used in each monitor:

Monitor 1 : Dell 2007WFP 21" -  CCFL
Monitor 2 : Benq BL3200 32" -  White LED
Monitor 3 : Dell U2713HM 27" - White LED

I've learned through trial and error that if you limit LR & PS to only use 2 cores they run more smoothly than on 4 or even 6. to do this first start the program, than open task manager. Click the details tab and right click on Lightroom and choose set affinity and select cpu 0 and one. leave other unchecked.

FWIW: On Samsung ssd's the samsung magician turns off superfetch when set to performance optimization as it claims to slow down program loading. I've found through testing it doesn't, it speeds it up.

Have you actually tried limiting the cores on a quad core system? I just did on my i7-860 Quad Core system and using only two cores slows down all of the controls in the Develop module. I believe this is only helpful with systems that have processor with 6 or more cores: https://feedback.photoshop.com/photoshop_family/topics/lightroom-clone-and-brush-tool-can-not-stress...

Most all of LR's operations are CPU bound so It's highly unlikely the SSD is affecting LR's performance as per the tests here: http://www.computer-darkroom.com/blog/will-an-ssd-improve-adobe-lightroom-performance/

I have just turned off six of my 8 cores and for the first times for months I have been able to edit images, using a lot of local adjustments and spot removal, for over 3 hours without having to shut LRCC down and re-start or even notice any significant slow down.
I had got so desparate that I have taken a subscription to Capture 1 version 10. I was starting LR every 5 or 10 minutes prior to working on just 2 cores. I hope this improvement does not disappear with the next update!!

Yup, works for PS also. Only pain is we can't script it somehow so it's automatic!!

I am not seeing you posting the Lightroom system info here. When Lightroom felt slow for you, is it slow right at the beginning after you launched Lightroom or does it gets slower over time. What is the typical size of your raw file? Which camera model?

Ok I've done some really intensive tests with lightroom and it's definitely problem with Lightroom itself and optimization, or lack of one.

So Cache size iz 250 GB on my Samsung 960 and i got 400GB of free space on the disk. 
I've imported 1:1 previews and smart previews.

1. When the "Use Graphic processor " is turned ON ( i got new N vidia 1060 6GB supported card ).
The crop tool is stuttering and its very slow.
The radial filter is ultra fast and responsive! 
The brush tool is something in between.
Switching between photos, applying presets and overall workflow in develop module is ok in the beginning but it get's slower and slower very fast.  Turning off Lightroom helps but just for short time. I got only 130 photos in catalog . Optimizing doesn't help much.

When i am in library module and i want to go trough photos with arrow keys on keyboard everything is going fast ( Loupe view ). But when i press F ( Full screen mode) and switch them with my keyboard little faster everything falls apart and lightroom is painfully slow. If i press arrows too fast it even wont change the photos. But with scroll wheel on mouse it's little faster.

2. When the "Use Graphic processor " is turned OFF
The crop tool is working ok.
The radial filter is very slow and stuttering.
The brush tool is working fast.
Switching between photos, applying presets and overall workflow in develop module is getting slow very fast too ( after editing 20 photos ).  Turning off Lightroom helps but just for short time.

The full screen in Library module is slow no mater what i do and what kind of previews i've imported ( minimal, standard or 1:1 ).

This is really terrible :(

Since you mentioned that you do video editing, can you try the following to see if Lightroom can sustain the higher performance longer.  Try to clean Lightroom's video cache folders: 

In Windows Explorer, navigate to the two folders “C:\Users\your account\AppData\Roaming\Adobe\Common\“ and “C:\Users\your account\AppData\Local\Adobe\Lightroom\Caches\Video” and just delete both folders? Then restart Lightroom.

Any video cache files that are needed will be regenerated when requested. For a related thread for the issue, see https://feedback.photoshop.com/photoshop_family/topics/lr6-8-memory-leak. You might have other issue with your setup. Let's verify one by one.

Hi Simon.

I don't do video editing, but i plan to do it in future.
I am power Lightroom user and use it heavy for photo editing. I must say that i am really really disappointed with Adobe and lightroom. 

I built very expensive machine just to speed lightroom  but it's even slower. I think that it is about time that adobe do some real work and program Lightroom form the beginning for multi-core processors and tasks.....the time was few years ago and still nothing. Adobe does not have real competition  so they don't care. 

Trough this week i tested lightroom much more, read all the discussions on forums with so many people complaining  about very slow lightroom. I went to few other fellow photographer just to compare and I found that it's mostly the same.

I imported 300 photos in my new catalog and started editing and it's so slow it really drives me nuts ant want to switch to other alternatives because when the wedding season starts I don't want to loose so much time on slow program.

The funny thing is that some tasks work better with GPU turned on and some with GPU turned off.  Develope module is painfully slow and full screen view in Library too.

I will record a video of my work in lightroom  next week when i have the time, just to give you more info.

Hi guys,

So here are few new things that will maybe help the others who are thinking about buying new Computer just for Lightroom. I've been doing more tests trough the week and nothing helped.

I've tried Lightroom on different computers ( PC and Mac ) form my fellow photographers and it is the same thing. But I did see with my own eyes that same versions of Lightroom tends to work faster on Mac even on lower specs machine. Need to ask Adobe why....

To get all divers issues out of the way. I have all the latest drivers and Bios updates for :

  • Motherboard
  • Nvidia GTX 1060 Graphic Card
  • Samsung 960 NMWe Drivers and Firmware

I got my Windows 10 and all the programs updated to the latest trail Version form Adobe Cloud.... Lightroom CC 2015.8 version.

Adobe programs like Bridge, Photoshop and Premiere Pro are working fast and without any problems.

Other programs, windows apps, games ect. are running perfectly and very fast too.

I tried few clean installs of Lightroom on Samsung 960 M.2 and on my old Samsung 840 PRO SSD. The results are the same. So let's begin...

1. If you have 3 monitor setup you CAN'T control output for the second display. This is really annoying because in my case it always displays picture on the left monitor and i can't switch the cables. You can change main windows on different monitor but if you press outside for a second it goes back to default position.

2. If you are using bigger monitors with higher resolution (mine are 2560 x 1440 ) with lightroom in Dual monitor setup ( or second monitor screen ). Lightroom is going to run slower. Sliders, full screen mode, previews, syncing, library...everything.

3.For me importing 1:1 previews + smart previews works best in Library but it is still slow. If I use full screen ( F key ) and pres arrow keys or mouse a bit faster Lightroom just can't keep up. If i have the second display it's even worse. One display changes the photos, other stays on the first photo until i stop, and then switch to last photo selected.
Full screen mode is useless for me. Lights out ( L ) without the tabs on the side works much faster.

4."Use Graphic processor " option for acceleration is pure lottery and works random in my case. Some tools like Gradients ( normal and radial ) work super fast when it's turned on, but then Crop tool and Spot removal tool are choppy and very slow. When I uncheck GPU it's vice versa.....it is crazy. I can't get that all tools work the same and fast.

5. I have only 155 photos in my Catalog and Lightroom gets slower and slower as I start to edit in Develop module. Btw i have 300 GB of dedicated free space just for ligtroom on my M.2...that should be ultra fast. But for some reason the only thing that helps is if i Quit ligtroom!!! Syncing gets slow, switching to another photo gets slower, brush gets slower to the point i don't want to edit anymore. Optimizing catalog doesn't help but on the other hand why would i optimizer catalog with 155 photos.. i don't want to think what is going to happen when the season begins.

6.Importing and exporting is Slow as hell but I don't care about that because it was always been like that and i just leave my computer and go do something else.

With all that in mind i started to look for other options so i installed CAPTURE ONE pro 10 trail and I was blown away form the start.

The first thing that struck me was SPEED. Importing, editing, sliders, syncing, exporting, everything is very fast. I've imported 400 old photos and started to play with the sliders, editing and syncing...everything works so much faster than lightroom.

The other thing i've noticed is that you can choose monitor ( if you have 3 monitor setup ) for second display and that changes are instant on both monitors!

Some sliders and color management are more powerful too.

So i decided to run a little test....import ( 1:1 previews ) and export ( full size ) of 155 photos ( 20 mpix Canon 6D ) with the same presets.

Lightroom CC Import 5:40 , Export 6 : 32
The usage of my I7 7700K Processor on 4.8 Ghz was from 80 - 100%....32G Ram usage was 17-22%. While importing and exporting in Lightrrom my multitasking on computer was much slower because of High processor usage.

Captrue One Pro 10 Import 3 : 54, Export 2 : 12 !
The usage of my I7 7700K Processor on 4.8 Ghz was from 42-60%....32G Ram usage was 21-24%. While importing and exporting in C1 my multitasking on computer was fast.

That only shows how much is Lightroom badly optimized and uses prehistoric code. Adobe is making so much money but they don't care about costumers and complaints. The optimization should be made long time ago  The worse thing is that i lost so much time trying everything but at the end it's just badly optimized lightroom.

So if you are planing to buy new PC or Mac with fastes disks just to speed Lightroom, my advice is to save your money because bottleneck is going to be Lightroom 

I spent only few days in Capture One so I won't make any fast or harsh dissensions. I will test everything and choose if i will switch. I've read on Capture one forums that there are some bugs and problems with people losing all catalogs settings.
If Lightroom had 50% speed of Capture one i would be happy as a child, but why would it be simple 

Sorry for the long post, but i hope that it might help somebody.

Man,

I have the same problem now for more than a year....I just dont want to open LR anymore, its so sad that i still have to....

I got pretty much same specs....3770k @4,7ghz, 3 ssd's, gtx1070 bla bla bla...computer should easily handle that...but lightroom uses just 20% of all that...

Everything you say is true..everything is happening on my computer here toooo...

*the troubles with multi monitor setup
*the slow down after 30min of work until its just not usable(and i mean not usable as the screen goes white)
*color profiles get mixed up if i alt tab out and in
*applying presets allways work on the second attempt..

dont get me wrong, i am no programmer but i am good with software and hardware and i tried everything but it just dissapoints me with every update more...i uninstalled,reinstalled, i keep my catalog very small, i optimize and so on...nothing helps...its so frustrating i cant actually believe it...

adobe never aknowledges the issue, doesnt improve it, literally does nothing...thats actually the worst part....i paid money for a programm which has become broken over time....

i dont know what to do anymore but its good to see that i am not the only one

thanks for that :)

Here we are almost a year later and the problems still persist. It's unbelievable that LR is still one of the worst written major software for 10 years now...It's unfortunate that it's the one we use the most...:(

Hello Kanaye,
On my MacPro, I have no speed/display and other kind of problems.
Will confirm what you say but I can't compare, I am only in App computers.

Here under you can see the config of my main computer.
Any figures that could (i hope) help you

About LR:
- My main catalog is having  +/- 34.000 pictures
- I have many collections and intelligent collections too. 
About computer usage:
- Lr processor usage is varying between 85% (at the start) to 3% of processor time.
- There are very short pics of +/-290% when calling a plugin or starting PS or DxO.. (just as info)
- Lr Ram usage is +/- 1,2Mo and goes at  +/- 600Mb when launching LR  or calling a new Lr module or a plugin and finally +/- 400Mb when leaving Lr

Speed problems:
A few times ago (let says 6 month) I have had a speed problem. After deep search, I find out that there were to origine of this slowdown. Out of that, I newer got any speed trouble since I am using LR (from V2) and LR CC

1) The Data base was busy for reorganisation and it took a while. 
- The intelligent collection do take a good part resources when you try for instance to modify a lot of Key Words. After an hour of modification, LR is hardly going down. Because it tries to reorg the library any time a modification is applied. 
- An other speed slow down is related to the thumbnail size. I you tend to use full size, it will take several computer resources.

Solutions I applied:
- I make a daly save of my catalogue so that the Library reorganisation is done at every Catalogue save.
- This was enough for me but may also decrease thumbnail size.
  


I am having a two Eizo screen config 27inches


I hope this will give you some ideas

Hi, 

specs wise kanaye's cpu should be 30% faster than my 3770k which also should be  more than 50% faster as your xeon (nehalem) i guess...graphics cards wise it should be the same difference....

so hardware wise it cannot be the problem because all of us should have enough computing power to handle the files...

maybe its not a problem on mac, maybe its only a problem on win10.....

but i am pretty sure it has nothing to do with "using" LR wrong becaue as i said...my catalog (and i think kanayes also) is much smaller than the one you use. I am talking of maximus 400 pics in my case...because i keep it always to a minimum.

i do reorganisation allways and also save it when asked.
thumbnail size is not the deal...because it does not matter what i select...
i dont apply different noise reduction to the initial preset (which also would decreases performance hugely) and i do not apply any lens corrections in advance...

it just gets kompletely hung up after half an hour or so....its unbearable...

Stefan, did you tried on an other window PC? You are right, My xeon must be slower than yours PC.
Try isolate the origin. I would say, LR is not a problem, I have friends that are using LR on a similar PC as yours (win 10), and it run very fast. So the problem must be elsewhere. May be in relation with the OS installation.

Might be worth a shot..it is not easy to do though...cause i would need a similar other machine in terms of software and i would need a similar environment...in terms of ssd's, presets and so on

my computer runs fast...i have the figures...one can benchmark(and i see on other programs)..i do invest quite a lot in a clean system and clean drivers, no bloat ware and so on...i would describe myself as nerd....and every single thing which was written in this thread i allready tried before...except the affinity tweak to 2 cores...so you probably can see my frustration....

the thing is...i dont doubt that LR runs smooth on other machines but on many it is not....

so is it now a LR problem or a Problem of the hundres of different hardware configurations that exist?...this is probably not comparable with mac...because of their relatrively small pool of hardware they use..everything is much easier to programm for... in any case one can allways say..."its not a LR problem because it runs smooth on my machine" but there is more to a programm code to just run smooth on some machines...


 i can observe that LR has in general a SPEED problem...look at the thousands of threads if you just google "LR TO SLOW" or "LR not fast" so nobody can say that everything is ok with the code of this Programm...the one thing i hope for is the "magic" tweak that solves all that...or that adobe for once says...."hey guys...we know the issues...were looking into it.

something we didnt talk about jet....is the filesize of the raw...it should not make a difference but it might also have..i for myself have 55mb nefs with 36mpx...and these of course do process slower than my 12mpix files before...

still were in 2017 and the specs of hardware is easily able to handle that...just LR appears to be not able to...

Try the following:
Modify the colorimetric profile used by default by windows 10 for the screen and reset a profile srvb or rvb.
Look also to the use the same color profile on LR. The best should be to use RVB. You may try to use the last Adobe profile ProphotoRGB

Hi there, I don’t remember so much about Windows but let me tell you the following ideas:

So much memory can not be handled by a 32 bits operating system, make sure you have Windows 64 bits.

Use the other monitors to “extend screen”, not to duplicate screen.

Use NVIDIA Control Panel and search for “3D Configuration”.  Pick the tab “program configuration” or something like that and search the Lightroom app.  Now assign the “Use NVIDIA processor”

In Lightroom 
/ preferences / performance : set the “Use graphics processor NVIDIA”

/ catalog settings / metadata : disable “automatically write changes into xmp”

Download the portable version of CrystalDiskMark Disk Benchmark to test your HDD speed (I'm not sure if it is suitable for SSD)

I hope this could help.

HI,

Win 10 64bit -> check
16gb ram -> check
extendet screens
(of course) -> check
graphics card powerplan --> check
LR use graphics processor -> check

Hey there, i ́m glad to know that i ́m not the only one with this issues. My problems are nearly the same with LR and WIN10. And i also built a very fast setup for speeding up LR. Well, a waste of time.
I bought a small macbook and LR runs like a charme. So i decided to turn my Win10 PC into a Hackintosh to see if it will work. It ́s really a shame. For fast work i use On1 Photoraw at the moment. But it ́s a completely different workflow and I notice that LR will be my first choice...
I edit about 1500 to 2500 images very often in one passage. My Xtouch mini and midi2LR in Lightroom are absolutely a speed improvement...

Thanks for all the infos you posted. This was very helpfull!

Hello there, i was able to turn my pc into a hackintosh. I'm using LR now wirh Sierra and it's really a difference to WIN10. I installed LR without changing anyrhing. And it's working without delays i had with Windows. Also my Wacom-Tablet is working. On Win i had a lot of problems. Only one issue came back. After exporting images several times the export did not work anymore. After starting LR again no problems. On Win i had to wait about 3-5 Minutes... Well, it seems to be right that LR is not made for Win. I will stay now with my hackintosh. Its running fast and smooth. More about building a hackintosh: https://www.tonymacx86.com/
