Linux will have better SMP scalability and will deliver better SMP performance than FreeBSD 4.x. This is because the Linux kernel has fewer coarse locks than the FreeBSD kernel. Linux doesn't scale as well as Windows 2000 because of both coarse-grained locks and the lack of IO completetion ports. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
