The issue is most evident when typing keywords into "tag" like fields. Sorry, I don't have the LR nomenclature down.
On further questioning, she sees performance issues in other areas too - a general slowdown when compared to LR3.
She has been busy rebuilding previews and caches, two suggestions from the user forum at Adobe. Her co-worker is much more computer literate and also has some strategies to try and smooth out her work flow. He uses the program on a Mac at work and on a PC at home, and while he says the program is slower than previous versions, he hasn't had the performance issues she has had.
I have also added a number of file exceptions to the virus checker that could be part of the problem. As I understand it, when updating metadata there are several files that get updated and not just one, so the exceptions will hopefully eliminate any interference from the anti-virus program. In fact, the behaviour seems very much in line with that sort of file access.
Yeah, we've checked for and installed the latest drivers for all components in her computer.
Another question that I have not been able to find an answer to, has to do with buffered vs. unbuffered RAM.
In an attempt to alleviate RAM issues, the machine was upgraded from 4 to 12 GBs of RAM, previous to my involvement. I have noticed that the original 4G is unbuffered RAM, vs. the 8GB added on which is buffered RAM.
My question is, is mixing the two types fatal? If not, should one type precede the other? In bygone days, it was said that slower RAM had to be installed so that it was accessed before faster RAM, to avoid problems.
Thanks for pitching in with suggestions on how to proceed!
