Uhm, I kind of forgot to say that we have about 20,000 users on the
system. With an updated OS (i.e. not RedHat 5.2), it's not a problem.
The performance problems we experiences were due to too many entries in
a directory (specifically /home/stud/$USER), so the home directory
structure was changed to /home/home$raid_nr/us/user which works fine.
sash is very good for you.
