Howdy Camera Bits,
I am opening several subfolders with between 1,500 and 3,000 NEF files in them in total. I am then filtering by rating so that I am dealing with 150 to 300 images and tagging them using a code replacement file. PM does fine and chews right through them until I change focus to another program. That could be to look something up on the web, or just match an athlete name with a number in an Excel sheet. Coming back to PM causes the program to become unresponsive for 15 to 60 seconds. During this time, one of my CPU cores registers about 30 to 40% usage. That is it. It is slowing me down quite a bit.
I realize I am pushing PM fairly hard here, but it can zoom through photos and tag just fine. Pop out of PM to a browser, or Excel, or a text editor, and it does not want to wake up again.
Win10, PM 5 Build 18610, Core i7-4790K, 16 GB RAM, SSD drive for OS and programs, photos on NAS running ZFS file system over gigabit network (although I have noted similar behavior locally, too)
