I don't know BSDI at all, but I would imagine that there is a vmstat and
iostat command on that OS. Use those to see whether you are having a
swapping problem or a disk I/O problem. Given the number of users and the
amount of RAM you have, I wouldn't be surprised if the answer was both.
Also I don't know how your disks are laid out, but I would strongly
recommend putting I/O intensive directories (like your mail spool perhaps)
and filesystems on their own disk.
