    Panorama merge slow after app has been open for awhile.

      Hey Everyone,

       

      I've noticed for a long time that LR has some memory-leak style symptoms after it's been open for awhile. Normally this was after at least 30 min but lately I've noticed it's supremely slow after building even just a couple of panorama images.

      I also notice that the CPU utilisation doesn't max out anywhere near as much - and yes, I've checked that my 32gb of RAM isn't maxing either.

      Here's what it looks like when I build 6 HDR dng files on a fresh start of LR.

      Take note of the small Memory graph on the left, nowhere near capping out.

       

      TOTAL TIME: 45 seconds

      After about 10 min of building various panorama's it eventually slows down... here are the same files built again after I noticed the slowdown

      You can clearly see the RAM doesn't get anywhere near maximum.

      If anyone can help me on why this is happening I'd be greatly appreciative. It's frustrating - actually, it's almost pointless to persist - having to restart LR constantly.

       

      Thanks in advance!
