I have a mVAX II running Ultrix 3.0 as a boot node, and 2 mVAX 2000's,
and 2 VAXStation 2000's booted diskless off of it.

the mVAX is only going to be a server, no user logins.  It will handle
news, mail, etc.

Has anybody played around with what's a "good" set of paramters to configure
the kernel to?  Since I want the mVAX to use as much real memory as possible
for buffers, should I crank up the MAXUSERS stuff?  what about the per-user
process stuff?  Should it be high numbers or low?  Are there some undocumented
things I should set?  What about nfsd's?  The manual suggests two, I've tried
4, and can't really tell a difference, other than the load average on the
mVAX goes up.

I've played with some of the stuff, but I think it's a fairly subjective
thing.  I suppose I could get MUSBUS from comp.sources.unix, and try
various parameters, and such, but I hope somebody else has done this.

Mail responses to:
icsu6000@caesar.cs.montana.edu

and I'll summarize and post if there is enough interest.

Thanx in advance for any info or light you can shed.
