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

I could throw $20,000 at this problem and it wont fix it. It is a LR core thing. We have to wait for a new release or bail on Adobe. Try the competition, you will see it flies on your new ride.

I presume they are rewriting the core - it is called Lightroom CC.

Same problem here. 

Got the Surface Pro 4 with i7 proccessor, 16GB RAM and 512 GB ssd. 
It runs smoothly for like 10 minutes and then starts eating up my CPU and RAM. 
I actually need to restart my pc for it to run smoothly for another 10 minutes. 
I use this laptop for programming and video editing and never noticed any lag except for LR.

Maybe I should add that I started see the lag with the latest CC update. Never noticed anything like this on the previous LR CC version.

I hope Adobe fixes these issues as fast as possible as I otherwise love LR and would hate to leave it.

good to hear about noticing the slower issues with the latest CC update ... I just upgraded to a new i7 16gb etc and loving it until I started using LR ... feel so much better knowing that it's a software issue and not the computer ... on my old computer, I never did the upgrades and it ran so much smoother ... so makes sooo much sense that it's likely connected with the upgrade ... going to see if I can install an earlier version of LR before I try the Capture One

Yep, I've experienced the same problem with performance on a new Quad core laptop with 12Gb of RAM, 4K screen.  It slows down over time, stutters on brushes etc.  The latest update has helped a little but not massively.  Convinced it's the software.

The only slowness I'm experiencing with the brush is sizing with the bracket keys.

I'm starting to feel that all the LR problems are just for us PC users with 4K monitors. There's obviously something very wrong with the LR team as they haven't been able to improve performance despite 10 - TEN - years of requests. 

What's happening over there? Why can everyone else at Adobe write decent Windows software except for the devs at Lightroom?? 

Same problems here...4K, i7 4770k, 32gb ram, dual ssd, gtx 1070. 

Beyond annoying at this point.

No only 4k monitor users. I have quiet good computer (3770k @4Ghz, 16GB RAM, 2x SSD EVO 850, GTX 1060 6GB) and new strong laptop (7700HQ, 16GB ddr3, m2 drive + ssd drive, 1050Ti). I use them with Eizo 23" at 1080p and on both LR works like on 10 years old computers. Sometimes I have to wait like 10 (!!) seconds after applying preset to see how it looks. When I move sliders, it takes about second to affect a photo. I don't have problems with CaptureOne, Blender, Photoshop, 3dsmax, they all run smooth like charm, but LR... I don't get it.
I have tried everything. Smaller catalog size. Clean windows install, clean LR install, GPU acc on/off, etc..

"I hope your good news will include 5960X processor support"

..............

My 5930K works reasonably well with LR Classic. What is strange about your 5960X behaviour?

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.

Hi Simon. I am having TERRIBLE issues with LR on my computer. Victoria recommended that i request access to try the prerelease in hopes that it will help. Local edits virtually kill my machine. Adjustment brush can take up to 20 seconds to complete a single edit. I completed a full format of my HDD recently, so all I have installed are bare necessities for school.

Alienware M17X R3
Intel Core i7 2760QM 2.4GHz (3 .5GHz w/Turbo Boost, 6MB Cache )
1.5GB GDDR5 NVIDIA GeForce GTX 560M
1 TB RAID 0 (2x 500GB) 7200RPM SATA 3Gb/s
32GB Dual Channel DDR3 at 2133MHz (4DIMMS)
Windows 7 Professional (up to date)
Adobe CC Student Subscription

@SimonChen - can you invite me as well?  I looked on adobeprerelease.com and couldn't find it.  Also, if we don't participate in the preview, how do we know when *these* improvements make their way into a production release?  there may be other performance improvements, and multiple releases before these are introduced, so would like to know.  Will hold off on buying a new pc until this improvement hits production.  Thanks!!

Artur, while Simon may not answer in time, I can say that you cannot talk about beta here. You are under NDA when in the program and it should only be discussed there.

I'm sure it would be fine for now. If they read it at some point, your message would be an apparent request for it to be deleted. If it's not, then nothing to worry about as you didn't know.

Simon, is there a way we can see what has changed in the build?  I need to replace my i7-2600k system, and trying to decide between i7-8700k (6 core) and one of the i9-79xx variants with even higher core counts.

I'm glad there is a silver lining at the end of this thread... I too am trying to decide on what new machine to build to speed up Lr.  Can I please get access to the Beta to test my current machine.

@SimonChen: That;s great news!  Will the "optomize lightroom" help document be revised when this goes to production?  it currently says "up to six cores".  This will be big!  I wonder if it will be equally beneficial to both Windows and Mac.  Most of the posters here look like Windows (like me).

That's not working Simon. There's got to be a problem on the back end. I've been trying to get in to that PR for the last day or so too.

That is weird. What happens if you quit the web browser, relaunch it and goto https://www.adobeprerelease.com and sign in there.
 
There might be some cached web page.

I like to provide a good mystery. ;-)  Cleared the entire browser cache. My best guess right now is the invitation was sent to a different email address than the one I use for PR. Working with Priya to try to solve it, but is anyone else having trouble also trying to sign in with a different email address perhaps?

Hello everyone I meet exactly the same problem of slowness on Lightroom CC that you all. I set up a nice machine and Lightroom is also very slow after 10 minutes.
My configuration.
Windows 10 64 B
Asus premium motherboard Z 270 A
Intel Core I7 7700 K
RAM corsair 32 GB 3000
GTX-1060 6GB
1 HDD TB
2 X Samsung M2 960 EVO 500 GB
I have been working on Lightroom for several years before updating to Lightroom CC, I had no problem. 
I tried everything as many of you, activate the graphics card, disable it. My Lightroom has always been correctly configured. I think now as many of you that the problem comes from Adobe and not from our machines. I hope that Adobe will quickly manage the problem because many people will turn to other solutions. I will thoroughly test Capture one Pro. In addition I subscribe to the Cloud at Adobe for photography and I find it scandalous for customers who use Lightroom that a solution is not found.

I have being trying to sync my photo collection to Lightroom CC 2018 but since having the program some 6 weeks sync has not finished yet. I would welcome using the new beta version if I could be included in any trial

The time it takes to sync is limited by the upload speed of your internet connection. https://www.speedtest.net is an easy way to check how fast your normal upload speed is.

It's not always a reason. I have 300 Mbs download and 100 Mbs upload and sometimes I can't sync 2-3 photos for hours. I add photos. but sync doesn't even start. When I click sync icon, the app shows that everything is up to date, but after hour, sometimes more, it just starts. I have added 20 photos from the last concert, but only half of them are synced now, and it was like a week ago.  Rest doesn't want to sync at all.

Victoria you are not correct. When I shut down everything except LR CC 2018 and leave it on all night I find it has uploaded only 30 or 40 photos. A dial up would be quicker. I am on a solid state HP Spectre with an E7 chip and wifi is fine with all other services including Onedrive (which I suspend when using LR sync).

Most online services rate limit traffic on their own to keep the demand for their resources in check.  Although access providers (cable, fios, uverse) do have moments of congestion, they typically are not the bottleneck if you have chronic throughput issues.

1 year on, this issue is still here.  check out this thread:

https://forums.adobe.com/thread/2396874

There has been no feedback from adobe on this issue on that thread. I am now told hat adobe do not read or reply to their own adobe.com forums, which explains why so many issues are not resolved.

For me, lightroom recently is unusably slow on the the highest end HW.
