Depends on what you're trying to do with it, and what sort of FreeBSD box you're talking about. A VLB '486DX2/66 will just about keep even with a Sparc 2 otherwise similarly configured; I don't have any data on faster Sun systems as just about everything around here is an Alpha. > I guess so but physical ram is expensive while swap is cheap so > like isn't there a point where you can just put a number for the physical > memory and just use swap the rest of the way and it will work fine? If your working set size significantly exceeds your physical memory size, it doesn't matter how much swap you have, you're still going to thrash. > -Vince- vince@kbrown.oldcampus.yale.edu - GUS Mailing Lists Admin -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] My car has "demand start" -Terry Lambert UNIX: live FreeBSD or die!
