Lightroom 6 / CC2015: Very slow UI response with background export(s) running

  • 45
  • Problem
  • Updated 11 months ago
Lightroom 6 / CC2015s UI reaction is very slow / sluggish when a background export is running. When three exports are running, the development module becomes virtually unusable.

In Lightroom 4 or 5 it was no problem at all to start up to three or four background exports - of course the UI, especially the development module, was considerably slower than normal, but definitely completely usable.

LR Version: CC 2015.0.1 (with 6.0.1 update), on Window 7 64. Processor is an i7-2600, there is 16 GB RAM. RAM does not seem to be exhausted, LR6 uses about 3...4 GB with 3 parallel exports.

Edit: It makes no difference whether GPU usage is turned on or off.

That is great news ! Hopefully they will come up with good solutions.
Is there any formal Adobe reaction to the many complaints ?

I have moved the installation destination to this drive, even the cache and database. My images is on a mirrored 2 7200 rpm, and the performace is awful!

I'm fairly positive that it has nothing to do with hardware. The two computers I use for processing photos were built by hand, purposed for editing specifically. They're rendered worthless after less than 10 minutes of use.

My Macbook, which I've used without a problem for the past year, is a complete waste of time to even consider using now.

It's definitely not hardware.

Strip 1 (Mirroring) can improve reads, but never writes, they equal basically that of a single drive.

I can't even select four images to group caption without it going in to a minute long "calculating" session.

I am having the same problem. Since updating to the most recent Lightroom version, any action, especially export, slows EVERYTHING done.

ok.... so.. did they patch something because today my Lightroom is flying... working without a hitch, acting like it did on the first day.

I've done absolutely nothing. I opened my macbook and started editing and it's perfect...

I see no difference in performance and i'm on it every day. i've not seen any updates come thru creative cloud so there may be perceived changes. I will say turning off face detection and address lookup helped a small bit a while back, but once the database of faces is built, it shouldn't have to run on anything other than new imports. hopefully we'll see our first patch soon...

I want to go back to 5.7 and I am wondering the best way to do that. I have my old catalog. Do I simply open up my LR 5 catalog and reimport any photos that were added after the upgrade? Will the edited xmp files work in LR 5.7 or will I lose any edits made on the files in the meantime? I have close to 20,000 new images that will need to be imported and I really don't want to lose the work I've already put into them.

Any suggestions from anyone would be greatly appreciated!

Hi Michelle, most of the edits should be fine, but not the elements created using the new tools (like dehaze). Well - you'll still be able to access those edits in camera raw (access through Bridge), just not in lightroom 5.7. Your metadata will still be there, including keywords, labels, ratings, etc.

And ya, just open your old catalogue and add at current location. Turn off file renaming and any metadata additions in the import dialogue. Maybe don't do 1-1 previews yet - at least not for the 20,000.

I installed lightroom 6 last week and using it today it was very slow. Wouldn't even load thumbnails.

I found that version 5 hadn't been uninstalled and the short cut I was using pointed to the old version. I did an upgrade and my expectation was that LR5 would uninstall and be replaced by LR6

Now I am actually running version 6 - all seems well.

Hope this helps someone else

Without question Lightroom CC 6 has some major software issues when it comes to exporting images and speed! I'm so glad I found this thread that proves this is not an isolated case or a hardware issue. I can only hope for an update in the very near future to resolve this issue.
Example: currently as a write this piece I am exporting 115 raw files @350 dpi and saving as a JPEG. Exporting files from an external Thundetbolt RAID drive and saving images to a USB thumb drive. In the past (using the previous version of Lightroom) I could do this in less than 5 minutes. I have now surpassed the 1 hour mark (just about complete) WTF!
I'm running a 2014 MacBook Pro; SSD, 2.3GHz i7; 16GB of ram. Using same 5D MK III, same in camera settings, same SD cards, same settings in Lightroom; ....SAME EVERTHING!...and getting ridiculously slower exporting results.
Adobe please resolve this issue ASAP

Rikk,
Two valid questions and no I have done neither of the two due to the fact that I just stumbled upon this thread just a couple hours ago and wasn't sure if others were having the same issues. I'm pretty certain that my preferences are most likely set to the default settings but I will have to check and verify.
The uninstall / reinstall would be a simple solution and any easy fix ..... If it works. Willing to try anything at this point.

Rick, firstly, thank you for writing in here. It is much appreciated.

I've done both reinstall and preference resets for both of my personal systems, but not on the school's computers. With both lightroom 5.7 and CC running on the same systems we're getting insane time differences - simply put, lr cc isn't useable on any of them (I'm running high end PCs at my studio and we use the latest Mac pro desktops at the college where I teach).

As I'm sure you can tell from many of the coments here, most of us are pro shooters who deal with large volumes of images, and most of us have been using lr and other Adobe apps for quite some time (17 years for me with PS and LR since the beta). The general feeling is that we've been brushed off as a lunatic fringe when, in fact, we're the furthest group from.

Any real help you can give us will make a world of difference.

Denni, can you give me a detailed specific example and an elapsed time for one of your machines (include the machine specs) and I will test against it to start pinning down possible solutions?

Hi Rikk,
Thanks!
I'm only able to check one machine today, but will add another tomorrow. I won't have access to the Mac Pros until next week, but I can send you that info then.

This machine is a PC running Windows 10 Pro (speeds for 5.7 and pre update CC were the same with Windows 8.1)
i7-4770 @ 3.4 Ghz, 8 cpus
32 GB Ram
GeForce GTX 660, 2 GB

There's a real speed boost in the latest update to CC, but it's still slower than 5.7 (substantially slower the more work it has to do).

Test With 10 CR2s from a 5D3. Face recognition was turned off.

Import, Convert to DNG, 1:1 Previews
LR 5.7: 52 seconds (faster by 15%)
LR CC (pre newest update): 102 Seconds
LR CC (after latest update): 60 Seconds

Export Originals
5.7: 1.3 Seconds
CC (Pre update): 8.5 Seconds
CC (Post update): 1 Second (!)

Export Full Sized Jpgs (adobe RGB, 300 ppi, 100 quality)
5.7: 22 Seconds (52% faster)
CC (pre update): 53 Seconds
CC (post update): 33.46

Export Jpgs 1200 px X 800 px (sRGB 72 ppi, 70 quality)
5.7: 8.46 Seconds (200% faster)
CC (pre update): 22.24 Seconds
CC (post update): 16.94 Seconds

Thanks again!

Rikk,
I have reinstalled the most current version of Lightroom (5.7.1 as of 31june2015). I re exported the same 115 images (1.35GB after export and average file sizes of 5760x3840@350PPI).
115 files exported from external Thundetbolt RAID drive to SSD drive on MacBook; Total export time of 4 minutes and 21 seconds..
Then tried exporting the same 115 files exported from Thundetbolt RAID drive to 2.0 USB thumb drive; Total time of 6 minutes and 10 seconds.
These same 115 images (1.35GB of data after export took over an hour to complete this task before reinstalling the most current version.
Much faster results and no more spinning wheel when switching from library module to developers and vise versa.
I'm back in business!!!!
Thanks Rikk!

HI Rikk,

Can you find out from the devs, why AVX and AVX2 support is missing from Haswell-E? It was there before the update.

2nd thing, is now GPU tests are failing where the previous version passed. If you made them more stringent, great! but it wasn't explained in the readme on the update.

It would also be helpful if LR could output diagnostics as to what test that would disable OpenGL support.

HI guys, I'm using the following:

imac 5k with 4.4ghz i7
4MB Radeon graphics
32GB
all files on Lacie raid array USB3

All apps on mac drive. The machine has no other app installed other than LR and PS

If I load a file of images in Library module I literally wait minutes as each preview builds, I can see in grid view all of the edits loading one by one.

This is on 6.1.1

GGGGrrrrrrrrrrrrrr

Lightroom CC has obviously major issues when it comes to performance. There is no more "flow" when it comes to workflow, every step has become painfully slow. I truly hope they get to solve these issues soon.

There must be some kind of memory leaks and bugs in rendering module. When I'm importing more than 1500 of 36Mpix RAWs from Nikon D800, LR 6.1.1 takes more and more memory, in 15% of job Win Task Manager says LR takes almost 10GB of memory and it is growing. Often I have to restart LR to become responsive and to free memory. And I'm not mentioning, that it takes hours to render 1:1 previews.... I'm running it over night, like in nineties, when I was creating first MP3 from CD and one mp3 tooks 1 hour to create... so now we are in "nineties" of developing modern RAW files... :D

In develop module, even when 1:1 previews are rendered, moving from one image to next one, moving back to previous image - showing previews takes seconds (first blured small preview is displayed, after seconds is displayed sharp 1:1 preview). Because I didn't any changes to photos, I do not understand, why it takes seconds to display preview. Any image viewer app is faster than LR.

I'm using Win7 x64, all updated, Core i7-3660K at 4.5Ghz, 2 SSD drives, 16GB of memory, so loading and displaying 1:1 photo preview must happen in a fraction of second.

Thank you Adobe for speeding up rendering and displaying 1:1 preview!

Ligthroom does something in the background even if nothing is to do.
Take a look at the CPU. At the beginning it works and is fast, but after a while
it uses permanently 25% of the CPU. ( i5 Windows7)

I found that If I create a new catalog, empty, the processor idle usage Drops down to near Zero. As soon as I import only one Folder with a few Nikon Raw Images, the problem is back.

it is very sad. Lightroom 6.1.1 is rather slow on my maxed-out Retina iMac. The old issues of slowing down as I keep working (while RAM utilisation shoots to insane amounts) is worse than ever. I have to restart every 15 minutes - half an hour to keep the response reasonable. The longer I work the worse it becomes, with beachballs, lags, etc.

Is there an alternative program to Lightroom? Exports are so slow that this is not a viable business application. This on a brand new rMBP, ssd, 16gb, mega CPUs etc..... Totally losing the plot now

Shura.Shum, I have seen people report 1 minute per image export and 2 seconds per image export and both call them slow. They actually had very different issues occurring. We can solve issues by understanding what a user is calling slow and whether that is actually outside the range of normal experience or not.

Denyer Ec, I normally see 1-2 seconds tops on D800 Zooming. I would recommend you uninstall Lightroom 6 and reinstall it. Then reset your preferences file by closing Lightroom, holding down [Alt/Opt]+[Shift] and relaunching Lightroom. Kill the preference file when prompted.

Please let us know what your zoom speed is after doing this.

Hi Rikk
I was exporting 494 images
NEF files to JPEG
File size settings limited to 10 mg
Colour space sRGB
The export was started at 8pm last night and I just cancelled it at 7am this morning and all my settings are set to ensure only the display goes to sleep. Just lost a day yet again and getting further behind

Well, Catherine, trying to duplicate a fairly close test.

Export 461 files as JPEG from Canon CR2 - Export with no Resizing, sRGB Quality 84 - 10MB file size limit, no watermark. Elapsed time start to finish 14:58. That's about 2 seconds per file.

Machine: 3 YO HP with 6 Cores and 12 GB of Ram- Raws on External USB3 hard drives writing JPEGS to local drive. My Macbook pro runs about 1.5 seconds per file but it is a newer machine.

That tells me you have something wrong with your configuration or your install, or possibly that you have a very slow device in the loop somewhere.

My advice to you would be the same as to Denyer.

1. Reset your preferences by closing Lightroom and then holding down [Opt]+[Shift] and relaunching Lightroom and accepting the prompt to trash or overwrite your preferences.

2. If that doesn't speed it up. Uninstall. Redownload the program and then reinstall it from the fresh download.

If, after those two fixes you are still exporting glacially, we will need to know more about the location of your raws and the destination of your exports.

Resetting preferences and re-installing did not improve the situation.

I am not even attempting to export at this point, as I have had to revert to 5.7 to get my work done.

The catalog resides on an SSD, and the images reside on a RAID0 Mirror set of two 2Tb Western Digital Black drives. I'm happy to assist in any way I can, as right now it's a giant pile of useless, and I'd love to be able to help make it work!

I have the same issue starting with the first release of version 6 to the current build. I've tried all the common fixes. All the cores peg out with a simple export of 2-6 raw files being saved as jpegs.

I also see a memory leak, the memory usage rises with each additional import until it suddenly drops as LR crashes. It crashed 6 times this morning, each time after doing several exports in a row. I've increased the raw cache to 10 GB hoping that will halp with the memory leak, but its still very slow to export, and I can never have multiple export jobs going on like I used to.

The new update 2015.2.1 does not solve the problem. Still lightroom is very slow.
It's not a problem of the HW it's a problem of lightroom.
Even if nothing is to do lightroom uses 25% CPU.

Something uses always the CPU.
GPU is off.
No face detection.
No exprot
No
No
No

Just adding to the general frustration, the fact that I used to be able to run Lightroom 5 onwards on a three year old, albeit fully spec'ed MacBook Air, and it ran like a dream. A bit slow during export, but that I could live with. Whereas now, I'm barely able to apply local adjustments without Lightroom acting like it's stuck in a pile of glue, hogging resources like a black hole bends light (or bends Lightroom, rather). Horrible, just horrible. I was concidering a hardware upgrade, thinking my computer is getting a bit long in the tooth, but when not even newer Mac Pros, iMacs and PCs armed to the teeth with CPU and RAM can handle it, then surely Adobe has made a colossal amount of cardinal coding errors since LR5. Corporate heads should be rolling at an exponential rate. Who needs shiny, new features when the core is so blatantly sub standard? That's adding insult to injury, Adobe.

I hope somebody notices the "heads should be rolling".

Not the heads of the ill trained junior programmers that are trying to meet their undoubtedly unrealistic targets, but the heads of the managers that decided to delegate and outsource development to a level of insufficient competence to handle an application that has become core to the workflow of thousands.

I agree that priority should be THE major concern, especially as files are getting bigger en bigger.

Changing the import process was a blunder, but I ask myself, did any customer ask for that.

I am not sure if this forum is read by Adobe. Is there any other place where we can interact with Adobe people ?

Is there a list of known issues and a managed process to handle them ?

This forum is read by Adobe, and is the best place to post. This forum also acts as the best place to find the known issues and their workarounds.

If you're having problems with the recent update, the best course at this point in time is to roll back to the previous update http://www.lightroomqueen.com/how-do-...
