LR Classic regularly uses 10.35 gig of memory on my M1 Mac.  I don't think the problem started with 11.1 though, not sure. The catalog is not large at all, and I'm editing a group of 12 RAW photographs.  See snapshot of Utility Monitor.  Is this memory leaks or considered normal?  I'm up to date on the OS, evverything really.   Thank you.  (PS: I was going to start a new thread on this but can't find the "new thread" command alas.)

Hi Art M.

LRC shouldn't be using 10.35G of memory! LRC (ver 11.1) uses 1.2 G of memory on  my system. Even Photoshop uses less than 5G. I don't know what the problem is, but that sounds like too much memory usage to me. Good Luck!

Excellent information.

My only question or concern is regarding standard-size previews. The heading says to keep them "as small as possible," but then says stay closest to the screen resolution. With so many 4k, 5k, and 6k monitors, this equates to rather large preview files and thus large Lightroom Catalogs, which can slow down a system.

Advice?

Warmly/j

How disable/uncheck the option to "Generate Previews in parallel" is expected to speed up operations?
