I also run it with idprio 5 and no other processes are idprio-ed (what a word). The main performance impact can be seen here when the machine is a nfs server. When copying the same stuff (360 files, 7MB) from this nfs server via nfs, it takes 39 seconds when rc5des is running and only 7 seconds if not. -Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
