No when they don't do anything, we just plain admit it. :-) Not running linux, I don't really know, but I would guess that they calculate it differently than FreeBSD. Your last guess is probably also on target. A process just sitting in select waiting for something to connect to it, really can't use much cpu, well I would say it shouldn't use any cpu at all. :-) John -- John Hay -- John.Hay@icomtek.csir.co.za To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
