I'm running FreeBSD 5.3 on my server and it has periods it's just 100% idle. I'm running some perl scripts every five minutes, but that doesn't put too much load in the machine either. As a matter of fact, it's rare that the machine has a higher load of 0.15. And I'm running quite a bit of things on that machine (Apache, MySQL, Postfix, amavisd with spamassassin and clamav, RRDtool, SNMP, samba and some more stuff). Though it's a Pentium 4 2 Ghz with 512 MB ram, but I don't have any other hardware. Figured I might as well make it a relatively fast machine. Either way, I never want another server OS again. This is great. Jorn
