Tuning information for ISC 386/ix

I recently installed Interactive Systems Corp's 386/ix version 2.0.2
on my 386 machine.  Unfortunately my machine has only 4mb and I'm
trying to run X.

I expected the thing to run slowly, and it does.  What I didn't expect
is that after a few hours of disuse it begins to hang terribly (not
swap, HANG).  Worse, even unloading the system (shutting down X and
logging all users out) doesn't restore performance to the system; this
morning I got it into a state where there were no users logged in but
a login from the console would time out.  This was distressing.

I think that this is the result of improper tuning (what in hell could
it be *doing* while it's hanging?), but I'm from the BSD world and
have no idea how to tune a SysV kernel.

If some kind soul could send me an mtune file that works reasonably
well (considering) for a system with 4mb memory, ethernet, and x11 (a
heavy STREAMS user), I would be very grateful.  Additionally, I will
be upgrading to 8mb and putting NFS on the thing, so any tuning
information for such a system would also be useful.

Please respond via email to madd at std.com (uunet!skuld!madd).  Thanks.
