Off the top of my head, I'd say less than 1 gig (maybe 2) or more than 256. With very little, you may need to start looking at some of the i386 tuning to things to scale back. But anywhere in the middle the defaults should work fine (I'm sure there are gains to be had from working at tuning, but probably not huge and probably very dependent on your particular hardware and workloads). -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
