Thanks Jim - I did that in Bitdefender, excluded every audio and video/photo extension identified to MC. When I reopen the program, it behaves well for the first few minute, but esp. when I'm adding Notes or otherwise adjusting the tag data, it quickly bogs down. There is a very distinct lag between the time I move my cursor to the file entry and the time MC allows me to highlight it, particularly when I'm trying to simultaneously modify tags or metadata for a group of files en masse.
Right now, having been at rest for a while, virtually all of the physical memory is being utilized. When I close the program, that is reduced by 50%. There's a more modest reduction in over-all CPU usage.
I can adjust the demand on the system when I don't adjust the tags as database info changes, but not completely, and that creates an extra task in going back to store changes when I'm done cleaning up the library.
Because of my storage array, I'd expect some modest response issue, but this builds to the point where the program barely functions when I've been working 30 minutes or so. (The library resides on NAS and 2 external drives.)
FWIW, here's system info from a day or so ago, with the program open, truncated for easier reading. I'm sure I'm overlooking something but would appreciate the help in identifying what it is:
