Lightroom Classic Severe Slowness and Memory Leaks!

I am running into the same issue. Sorry to say I can't add anything for help though. I have Windows 10 on a 6 month old Dell XPS computer with and i7 and 16 Gig RAM. Right now as I write this, the Develop module sitting at complete idle is drawing 2.7 Gigs of memory. Adobe, please help! Best of luck skyrunr and everyone.

The fix is to create new empty catalogs and import your old catalogs into them.  This is a real pain.  It isn't a perfect fix, but everything is working better for me!  It was in another thread so I wanted to post it here.

1. Update to version 7.0.1

2. Use of OpenGL instead of DirectX

3. Create a new catalog and import from the old catalog

4.  You have to set each new catalog's settings as desired

I'm running 50GB raw cache on an SSD drive, GPU, smart previews, high resolution JPG's, unlimited video cache.  I also set lightroom.exe to be high priority in Windows tasks.

good luck, lets get back to work!  (man this forum is awful, it doesn't tree/thread, it keeps jumping to the top, and I can't see what I'm typing...  ugh!

I made some progress!

Memory still spikes up a bit, but the program no longer bogs down!  Not all of these were changes, but I wanted to confirm all of the settings I had.  I can view, clone, zoom, navigate, and get work done again!

• Updated my Video driver to the non-whql version (AMD R9 2xx)
• Deleted all of the Lightroom preview folders (GB's)!  I'd say this was the main fix.  Note that there were duplicate folders for previews and for smart previews.  The smart preview folders have not re-appeared yet which I find interesting.
• Increased camera raw cache to 10GB
• Unchecked limit video cache
• Checked use smart instead of originals for editing previews
• Checked generate previews in parallel

UPDATE2:

• Installer of Lightroom Classic CC doesn't remove Lightroom CC; since my catalogs are updated I'm moving forward and manually uninstalled it.
  (Why they didn't name it "desktop/local/offline" instead of "classic" is beyond me!  Even just plain Lightroom would make more sense.  LOL)
• There is also an update to Classic CC which did not come up under automatic updates, no problems with it yet.
  (No easy way to preview what was in it from the cloud interface either.  You'd they were new to software or something.)

You may also want to try running the lightroom.exe as an administrator at least once.  I toggled this back off and didn't notice a difference.

I hope this helps others, please post your results here, good luck!

Adobe,

I have same slowness. I have adequate memory. Previous version was running much faster. Import runs slower than before. Your notes indicated faster previews, faster imports... What happened? Please address!

Thank you.

I have the same issue as well. i7 PC SSD 16Gig Ram.

After about 5 minutes of develop use, things like moving between images or using brushes slow down massively to the point it becomes pretty much unusable. Memory usuage in task manager shows lightroom up to 3.5 Gig!

To get around this slowdown, I am basically closing lightroom and opening it back up again every 10 minutes or so to clear the memory.

For an update supposedly focused on speed improvements.. this is far from it..

The speed is unbearable. How do I revert back to lightroom 6 this is absurd.
