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.

ASAP and Adobe are never used together, not even in the same thread, let alone paragraph or sentence.

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.

This is a great conversation that's separate from the main one, so I created a new conversation to continue the discussion.

Please reference the new conversation here: Lightroom: Changes to Processor Support?

... Is the current update (today) CC2015.1.1 also a performance update ?

I can answer my own Q,

Initial impression is that displaying 1:1 has improved markedly.

I'm seeing a speed boost, but it's still running much slower than 5.7 for me. A few post up I've detailed some speeds I just clocked.

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

Was it significantly faster with 5.7.

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!

I have similar computer with similar problems... It is kind of weird.

I am commissioned to shoot an event with the new 50MPix DSLR by Canon.

I don't even want to think about what is awaiting me next week in post production... :-(

I plan to make about 1K photos of which I will leave about top 300 from which then I will select about 100 depending on the crowd and their mood and moments.

Wish me luck! ;-)

To the topic: To speed up things, I'm trying to not view photos in serial way, but just to look to the possible candidates from a grid view.

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 disabled the option in Lightroom to use your Graphics Processor and it resolve most of my slow response issues.

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

How slow is slow? How many files? How long does it take?

I'm feeling your pain Catherine - 4ghz i7 with 32Gb RAM here (Win 8.1 64bit), and 1:1 zooming takes between 8-10 seconds on a 36MP D800 image. I've ditched LIghtroom 6 and gone back to 5.7 so I can get on with my work :(

how slow is slow? you guys at Adobe know exactly how slow your product is on current top of the line Macs with hi-res screens (4-5K). What you need to learn from us users, is that this kind of performance is not acceptable for a professional application.

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.

So am I. _The problem, whatever it is due to, has gotten worse over the last weeks. What is this? How can they dare not to fix this?

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

The new Update didn't solve the problem. Still lightroom uses permanently 25% of the CPU. :(
And the system reacts very very slow. NO FUN USING IT.
