P: Slow walking between photos in Loupe view

[stefantotev]

I've been noticing a big performance decrease after updating to 5.4 both my iMac Pro and MacBook pro with M1 Pro CPU. 

After I open the app and start working in the beginning everything is alright, snappy and quick. After a while (5-10 min or less) I experience slow loading of photos - when switching from one to another; when zooming and when switching panels. Sometimes this lag is around 3-4 sec which is very noticable. The GPU is doing its thing because the graphics are not choppy, but there's just a delay in doing the above mentioned processes. 

Anyone else experiencing such issue on Mac?

[EGingras]

Same problem here on an M1 Pro. It's absolutely horrible. Nearly unusable due to how slow it is.

Same issue on both of my PC's. Severely affects the work flow.

The engineers have asked if you can open Activity Monitor as you use LrD and monitor what is consuming resources. 

A video screen capture showing LrD side by side with the Activity Monitor set to its Memory Tab would be a big help.

Thanks - those were helpful.

Questions from engineering:

1) Ask if there is new hardware? i.e. New monitor. The specs say the resolution is 5120x2880
2) If this degradation is new to 5.4 (i.e. were earlier releases ok)?
3) The next time the performance problem occurs, have the customer generate a diagnostic log immediately after the degradation.
4) Do you have a lot of presets? Estimate for how many you've used/installed?

For LrDesktop Diagnostic Log

• Go to Preferences
• Account Section
• Hold down the [Opt/Alt] key to make [Diagnostic Log] button appear.

Let me know when you have the log ready to ship to us.

[stefantotev]

1) no new hardware. I use the built in screen of the iMac Pro. But this performance decrease also happens on my Macbook Pro 14" with M1 Pro chip. 

2) Earlier releases were fine. Problem appeared immediately with 5.4. 

3) I have generated the log.

4) I have 400 presets. But I had them in previos versions prior to 5.4 and no performance issues. 

I am ready with the log file. Should I attach it in a post here? 

[Rikk Flohr: Photography]

Thank you.

Share the log via Dropbox/Creative Cloud or similar.

If you don't want to post the link publicly, you can direct message me via the forum with the link.

Same issue here. workflow has slowed to a crawl.
Is there a way to roll back to 5.3?  I am unable to get any work done.

[george25229835105l]

Same problem.

[Kaan25178877ox3g]

I wonder if this is a similar issue with what I am having. I have an issue due to the high (around 400 like you) number of presets, for me it starts to happen the second I open the presets menu.

Could you try to disable your presets from the Manage Presets menu then try and see if you are having these performance issues?

[Rikk Flohr: Photography]

Log received - thank you. 

[EGingras]

Yes, this is certainly related to presets. If I never open up the presets menu, Lightroom behaves normally. Once I open it and scroll through a few preset previews, it slows to a crawl and will stay slow until Lightroom is rebooted.

[EGingras]

Have the engineers identified the cause of this bug?

[EGingras]

Is this fixed in Lightroom 5.5?

[Kaan25178877ox3g]

@EGingras I just tested and still having this problem. Luckily I have my iPad so I can at least work on things. Hopefully we get a fix at some point.

[gordono524822]

agree that the problem is releated to presets. Slowdown begins after using Recommended Presets and persists until restarting LR. Avoid recommeded presets and LR functions normally.

[Rikk Flohr: Photography]

Greetings,

Updates to Adobe Photography Products were released today and contain a fix for this issue. Please refresh your Adobe Creative Cloud App ([Ctrl/Cmd]+[Alt/Opt]+[ R ]) and download the updated version “.0”. 

Thank you for your patience. 

[Kaan25178877ox3g]

Thank you I just tried with my M1 Mac and it is working.
