P: Slow UI when using Mac and Custom Display Profile

@hursey :- Is it possible for you to share the screencast/ video recording of the issue that you are facing?

Thanks for reporting.

Unusable is the appropriate term. If I click in the scroll bar (ANY scroll bar) I get a spinning wheel 8-10 seconds.. If I engage a filter in the grid view (i.e. attributes, text, etc..) I could have the wheel for 30+ seconds.. 

EPIC FAIL.

😔

@davidmantripp  :-  Can you please provide more details on the slowness issues that you are facing? 

We have tried to compare apply develop presets to 1000+ images to compare the time between 9.3 and 10.0 but it almost took the same time.

Can you share the develop preset that you are applying on the images and if possible, a recorded video would be of great help.

Please share the dropbox/we transfer link and send it to mayugupt@adobe.com

Thanks for reporting.

Hey there,

 I've just updated to LRC 10.0 and the performance has become completely unusable  when my secondary monitor is enabled, performance is smooth with just one displayed enabled within LR.   Specifically the issue is 30 seconds of spinning wheel hanging time every time  I move between photos and making simple slider adjustments. 

 Previous to this update, i've always worked with my dual monitor setup with smooth performance.  

 
  My machine specs are  : Mac Pro (Late 2013), 3 GHz 8-Core Intel Xeon E5, 64 GB 1866 MHz DDR3, AMD FirePro D700 6 GB.  Macos Mojave 10.14.6   The one of my monitors is 4k.

I'm guessing the problem is coming from a GPU driver issue, though turning off GPU display processing worsened performance.   

So far I've tried:

doubling my camera raw cache size, creating a new smaller library,  a complete uninstall and reinstall or LRC (including the prefs) rebuilding my smart previews

 
Anyone else experiencing this? Or have any Suggestions?  
Thanks, 
-Jamie

In my experience, the slowdown seems tied to the Zoom level of the Loupe view in Library. Can someone else try this and see if they experience the same thing?

• With zoom 100% or greater, the performance seems normal.
• But with a zoom below 100%, it takes 3-5 seconds to switch between photos, and the spinning beachball appears.

Having similar issues. 2017 MBP, 16 GB mem (which is probably not enough), LR catalog on external SSD. 

I also attempted this and it failed. I've gone back to 9.4 and very happy to have the same speed I had before the totally useless 'upgrade' to 10.

@Rikk I uninstalled and reinstalled and ran it got real good for a while, but has since slowed down, but near as bad as it was.  Yesterday if I went from Keyword List to Keyword it would take 8 sec, today it was instantaneous  after the reinstall but now it takes 3 secs.

I called support and they asked me to start a new catalog and import a few images. It didn't fix the issue the library remains laggy and slow.

That is a thought. Only problem is, we have numinous reports of people creating new catalogs and having the same slow down problems.
