I found it. Kirk gets the credit --- softupdates was turned on in one of the machine's /usr/obj's and off on the other machine's. So softupdates improves buildworld times by a significant margin. I've turned softupdates on on both machines and am rerunning the test. I expect I will see an improvement closer to what Bob Bishop saw when he ran the test (7% or so) rather then 20+%. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
