@michal:

There is no LDAP involved here at all, we are using local /etc/passwd | shadow
for passwords. So that makes the delays in writing to disk even more stranger.
When we get below a certain number of users, then it starts working much
faster again. It appears to me to be a problem with interaction with disk and
networking.

Looking over the strace for vi-ing a file shows nothing unusual. It reads in
all of the configuration settings for vim and then opens the file. Today with
40 users, it's taking a good 4 seconds for the file to open. :\

The one thing that I am going to try is to install the vanilla kernel instead
of -desktop. It shouldn't affect us greatly, but maybe something changed in
there that is causing this issue. I'm kind of running out of ideas.
