This conversation has been merged. Please reference the main conversation: Lightroom: LR4.2 Performance Issues remain

i have 32 gb of memory and 32 core in 2 processors. i am using amd opteron processors, windows 7 64 bit. lightroom is up to date.
i have imported a small number of raw photos from a canon mark 2 - about 2000 photos. when i try to view the pictures to grade them, i can see the first 10 or so as quickly as i want, but after that, lightroom starts slowing down and saying "Loading...". The number that i can see quickly varies. Ihave set the preview to 1:1, have optimized my catalog several times.
This is a very fast computer with the c drive split across 2 SSDs. the 1 tb drive I am using to hold the photos is not an ssd drive. it is about half empty. Because of the way my computer was set up, some user data is not on the c drive where adobe expects it and apparently this prevents adobe bridge and photoshop from running unless i run as admin, but this does not seem to be an issue for lightroom.

Very disconcerting. My machine is much slower than is yours, but LR 4.1 was running fine on it. I upgraded to LR 4.2 and now the performance is painful, at best, and completely unusable, at worst. I had to down select to FOUR photos in a project (deleted all others) just to get to a performance level where I could edit. This is killing my productivity!

I am also on Windows 7 x64 and have the very latest LR 4.2 installed.
