Ok, there has been some discussion on large diskless clusters. Something
that relates to this: how should I configure the kernel on the server to
get the best performance ???

Let's describe the situation:

	    1 HP9000/370 server, 16 Mb RAM
	20-30 HP9000/340 diskless clients, 4 Mb RAM
	      There are no user processes on the server, only some additional
		daemons like "sendmail" and "nnmaster"
	      Most of the clients run X11


I've just increased some kernel parameters and I'm anxious to find out
what will happen tomorrow morning when time is there for all of them to
hack whatever they dreamed about last night into their keyboard :-)

Well, if anyone has experimented with tunable kernel like "dskless_*", "nbuf"
and "netmem*" parameters in an environment like the one described above or
has any suggestion into improving the server's performance, I'd really
like to know... I'll let you know if any of my changes turns out to be one
of the "I had better not changed that" choices.

	Thanks in advance,
