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

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.

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-...

For NEF files 1:1 display runs many times faster in Nikon software

I did find that creating a new database (based on my old one) eliminated a lot of speed issues. Exports still seem to suffer a lot, but other functions have plenty of speed.

My installation uses 0% CPU with a raw image opened but not actually working on something. All 8 cores peg out during a export. This brings other operations to their knees.

This reply was created from a merged topic originally titled LR Performance, Assign Preview/Export/Import/Move to lower-priority threads.

If I'm working in LR and running an (export / preview render / import / file move / metadata save / etc) then the user experience while interacting with LR degrades as these jobs demand more and more CPU resources.

For example, I'd like to be able to export images from one wedding, while starting color correction on another. Currently it's hard to use LR while exporting because the UI lags, sliders become less responsive, etc.

My idea would be to assign these kinds of non-realtime tasks to a separate thread that can run at a "below normal" priority, allowing me to continue working smoothly in LR.

My current only-kinda-workaround is to go into processes on my task manager, and assign Lightroom.exe the "below normal" priority. At least this way I can queue up a bunch of tasks, then go to a different app such as PhotoMechanic and get some things done there. Of course this still doesn't let me continue working in LR itself.

This reply was created from a merged topic originally titled Lightroom - Paused export would improve workflow.

The ability to pause one or all running exports would be great. When exporting a wedding I have often 12 or more parallel exports. Since the running exports drain the cpu it takes time and nerves to start the other exports and continue editing is out of the question.
It would be wonderful if I could pause all exports and keep working until the evening or a break. Then start everything and the computer can work when I'm not working on it.

It would be a major improvement for the everyday workflow!

I used to be able to run multiple exports, but with 2015CC, I can never get to the second one until the first is finished. It tales me a lot more time sitting there waiting for my pc to respond so I can do the next export rather than queueing them up and letting them run while I work on something else. Something is wrong here, it should not hog all cpu just exporting 4 or 5 images.

I'm not sure why my post was joined with this. I asked for a future possibility to pause/queue exports. That was more of a solution to this post since I can start multiple exports (sometimes up to 16) parallel. Of course I can't work in the development module anymore with an export under way. For that it would be nice to pause exports.

I use a macbook pro late 2012 (2,6 GHz i7, 16 GB RAM) and LR works fine with it.

LR really needs some deep review in speed and loads.

The performance for this last version is just horrible compared to LR5, will wait the current sync ends to roll back on 5, worst LR release ever, hope to see a update fix this.

Does anyone know how to roll back a CC Version? I can't find how to select an earlier version in this CEF Tool or whatever that's called.

Thank God it's not just me! I've been doubting my Hardware for a couple of weeks thinking there must be something wrong. i7 with 16gb of RAM shouln't be lagging like this. I thought it might be my new 5DR Raw files causing the problem. I really cannot believe how slow this LR6 is! I cannot work with this. I've got 10 shoots with around 6000 files to edit for my client and this is just unmanageable!
Adobe, can you just PLEASE add the 5DR Raw profile to LR5 so I can actually work! I feel like it's 1998!
I don't use CC, just the LR6 program - are there any updates or anything I can do to help at least while you guys work on a fix?

Latest installed update is 6.3

Try downloading the adobe dng converter (it's free). That will let you get a manageable file type out of the 5dr cr2s. You should be able to use LR 5 then. It's ads an extra step to your workflow, but it still might be faster than 6!

Thanks Denni, it seemed that the 6.3 update resolved things, at least for the last hour or two. Then all of a sudden my CPU shot up to 80-90% with my RAM at 60%! Task manager shows that it is JUST LR6 causing the issue. I think my laptop is going to have a coronary! I'll take a look at the dng converter, just never had to in the past. Thanks for the swift reply and help.

No worries! This stuff if driving me nuts, too. I teach photography at a college where we've got the very latest and fastest Mac pro desktops. My students are sitting there, twiddling their thumbs for half the class (or longer). And the school refuses to role back to LR5! I'm actually rewriting my entire course for next semester to exclude Lightroom. The performance issues coupled with the (now replaced) 'new' import dialogue have me really worried. We're trying to negotiate Capture One for our systems for next year. We obviously can't rely on Adobe anymore. Ugh.

Great shame. I have no idea what the heck Adobe are doing. I had to upgrade to LR6 just because of the new RAW's in the 5DS. Was quite happy with LR5 as the extras in LR6 are not really game changers are they?! Hope you get it sorted too. Currently uploading 725 5mb jpegs to Photoshelter via LR6 - 1hr45min and still at 75%!!!!! Not looking forward to exporting the Tiffs!! Might go on holiday!

Dear LIGHTROOM people. Can somebody PLEASE reply to the distressed users.

LR6.1 performs reasonable on my desktop, but no 6.x version does well on my laptop.

Why can NIKON display a full size NEF file in less than a second and why does it take LR up to 10 seconds ?

I have thousands of pictures of my last trip and cannot afford days of wasting my time.

Please do not ignore us. At least give a reply.

em, have you installed 6.3 which was released a couple of days ago? It should have solved this export issue. Of course, if you're having issues with general slowness, you may have a different problem entirely.

I have created a new topic, for performance, without running anything else.

Yes Victoria (and wow, thank you for your super quick reaction).

I have been posting in a wrong subject I fear.

My display comment relates to both library and develop view, without export or any other programms running on W10

Can't understand the described hard core slow performance of LR CC 2015.3

I do have issues when doing like 10 Exports simultaneously but without running Exports my LR is doing its job just fine. (Thats why I asked Adobe to implement a pause-function for Exports.) I can work on my pictures in normal speed (Development Module, Radial Filter, ...) and also the Export is at the normal speed.
And fortunately they just returned to the older, better import screen.

I use a 15" MacBook Pro Retina Late 2012 (2,6 GHz i7 16 GB Ram).

I've been having general performance issues since the 2015.2.1 upgrade, including the thumbnails in Library view taking forever to render. I tried reverting to older versions with no luck... BUT I just deleted my previews file " Previews.lrdata and restarted lightroom... problem fixed! I then regenerated standard previews and problem remains fixed!

I've been having the same issues as well since the lr6 update but today its has got so bad it is virtually unusable in develop mode. Its also acting quite oddly - creating temporary folders with one image at time on my hardrive and showing import photos in library in the wrong order and at times upside down. I've just downloaded the November update (not sure of the version number) so I will see how this goes

New update is even worse. 10-15 seconds delay is switching between images in develop mode. WTF??

When I have checked my hard drive I still seem to have lightroom 5. Lightroom 6 looks like it has just been added alongside it. 5 runs fine as well so I'm just going to go back to that again.

If isn't sorted soon I'll be switching to Capture One

thought it was the new version of windows10 that was the problem, untill i found this chat.
downloading a new version as i type, will have to wait and see what happens when finished.
