Well, I was only doing -j 2 on a 2 CPU system, so I may not have been fully stressing the system. I think my full buildworld time went from like 2:06 to 2:02 or some such. With -j 8 and the mb's removed it was 1:56 or some such. These are with WITNESS and INVARIANTS though. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
