P: Quick Develop VERY slow on my system (6 sec vs 1 sec in LR 5.7)

[FeedbackCommunityMember]

Lightroom CC
Quick Develop
When I make any changes to a file (D800 NEF) in Quick Develop in Loupe view, I get a message "Loading" for about 4-6 seconds (forever) before the change is rendered. In LR 5.7, the same thing takes less than a second.
Fresh install of LR CC.
System Preferences reset to default, just to be sure.
"Use Graphics Processor" enabled (no difference when it is disabled)
MacBookPro 2014 fully loaded (i7,16GB,1TBssd) OSX 10.9.5
No other software running.
This makes "Quick Develop" largely unusable!
Please fix, ASAP.
Thanks.

The new GPU assisted speed in Develop module seems to be working fine, is appreciated, and is getting closer to how it should be.

I am having the same issue. Suggesstions have helped some, but not fixed the problem. I have the new Lightroom CC 2015, but still have the issue when working on photos in the develop module. 1TB Solid State drive, 16GB of RAM, 2GB Video, Intel i5 2.4GHz processor. Even after rendering previews which literally took 10 hours, Lightroom is still taking 3 - 4 seconds to load previews on each image. May not seem like a lot but when you are sorting a wedding with thousands of images trying to find the best ones this can triple your work time. Please fix this Adobe, Lightroom was awesome up until these recent updates.

Try deleting the contents of the SLcache (C:\program files (x86)\Common Files\Adobe\SLcache. You need to sign in again and the folder will be repopulated with uptodate stuff.

It speeded up rendering of previews for me. LR CC was spending about 4 secs messing about in that folder. Now it doesn't and rendering is 4 secs faster.

Might work for you!

After running for an hour creating 1:1 previews, LR CC 2015 is now spending 2 secs trying to close the SLcache again?? What is wrong with it? This was a clean SLcache an hour ago?

[smauel]

All I can say is that I called Adobe Support and after an hour on the phone trying everything in this feed and others, including uninstalling & reinstalling, creating a new catalog, changing preview settings, pre-rendering photos, ect Lightroom CC 2015 was still taking 20 - 30 seconds to load previews. I downloaded Lightroom 5.7.1 again and the problem went away immediately. Previews load in 1 - 2 seconds without having to pre-render them, just like before. Not sure why version 6 is so slow but I will be using 5 until they fix it.

I've been having the same terrible slowness in the develop module. I didn't have this issue with 5.7. I have installed the very latest update, but still everything is really pretty slow and sluggish. I've turned off GPU support and that made a very small improvement, but things are still much much slower than in previous versions. I don't have anything new to add, just want Adobe to know that the others who have posted are not alone with this issue.

[acharnas]

Any word from Adobe yet on this? The latest LR update solved my other major problem (edits to tiff files were getting ignored), but this extrememly slow rendering is still a huge issue for me. It's especially painful when sorting thru an initial batch of images to make selections. Each image takes 5-10 seconds to resolve into focus, or longer. This makes it incredibly painful to sort thru a large number of images.

Adobe: please let us know if this is going to be fixed! As others have said, it was not a problem in version5.

I was hoping to hear from Simon after I listed all the details about my system and issues above, despite some somewhat helpful advice from Steve, I think we have yet to hear back from Adobe acknowledging these types of performance issues.

[acharnas]

I'm importing 145 photos this morning, and it has been about half an hour and still rendering is only about half done. (And this is from a 16MB camera, nothing huge).
For the first time ever, I am contemplating abandoning Lightroom entirely and finding another tool. I would be giving up a lot of things that I love about Lightroom, but at these speeds, it defeats the major purpose of LR for me, which is rapid handling of a large database of images.

Moved the installation destination, database and cache to this disk and have my images on a mirrored 7200 rpm discs and the performace is so awful. Tryed to made a smaller catalogue but nothing. I cant use this program and i really, really hope that adobe fix this!!

i5 3570K 32GB Ram and Samsung 830 256GB as OS

If you're on Windows with Intel CPU with AVX2 support (Haswell and Broadwell architecture), you would be affected by a performance bug in Lr & ACR that has just been fixed for the next dot release.

You can find out whether your Windows machine support AVX2, check it out in Lightroom's system info dialog. In the "Camera Raw SIMD optimization" info field, it would list AVX2 as being supported.

im mine copm it says

*Camera Raw SIMD optimization: SSE2,AVX*

[tomasnilsen.se]

And lightroom use 80-92% Cpu just in DEv. mode im not doing anything

[simonsaith]

Thanks. Your system is not known to be affected by the bug, but it could. Make sure to try out the next Lr 6 dot release when it is available.

[kenb0t]

I'm so thrilled to hear this, Simon - thank you very much for this update! Mine shows Camera Raw SIMD optimization: SSE2,AVX,AVX2

By the way, should I be manually turning off my 3way SLI GTX 980s to force 1 card for Lightroom? Please advise.

When will the next LR6 dot release with this fix be released?

[simonsaith]

You shouldn't have to wait for too long...

[simonsaith]

The current bug is unrelated to GPU acceleration.

[kenb0t]

hoping that's dev speak for "this sprint"

[acharnas]

Simon,

I'm using an imac (OSX10.9.5). Any hope for fixing the bad performance bug(s) on that platform, or is the upcoming fix only for windows? This problem definatly exists on the mac as well.

[Rikk Flohr: Photography]

Lightroom 2015.1.1 / 6.1.1 was released today. Have you tried to see if solves your issue? http://blogs.adobe.com/lightroomjourn...

[Ron_Hu]

2015.1.1 Notes:

Looks like AVX and AVX2 was removed? What used to be shown is now not shown.

Also GPU detection now fails also. HOW DID IT FAIL ADOBE? START PUTTING OUT SOME BLOODY DETAILS.

[kenb0t]

Lightroom CC 2015.1.1 is now available! Can't wait to try

[kenb0t]

Will let you know shortly

[PA_Photo]

Why doesn't the update show up in the CC Control Panel?
