I'm not sure. Once could argue that you get X% of the total CPU, which means that if you're normally allotted 20%, a single-threaded process would get 20% of a single CPU, and a threaded process might get 2x10% of each CPU (depending on whether or not the threads need to be on multiple CPU's, which may be the case.) It's an interesting problem.... Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
