:> No, it isn't. For a very simple reason: The resources users need to do
:> real work are very similar to the resources users need to hog the system.

:That has nothing to do with it. Not for cpu usage. If you have two users that
:are using all the CPU they can they ought to get 50% of the CPU each. Even if
:one of the users have 1 process and the other have 100 processes.
:
:Sun has a product for this, Solaris Resource Manager.
... and if one user is *supposed* to be running all those processes, then
what? Oh, let me guess: Now you are supposed to tune each user's account
independantly. For a system with general user accounts, this is a burden
on the sysop.
If one can't control one's users, one has no business managing them. The
last thing FreeBSD needs is some overly complex, sophisticated scheduler
designed to help bozo sysops stay on their feet.
