I figured out why my I/O rate was still high -- I also hadn't turned on softupdates for /var/tmp, but it didn't make much of a difference since I use -pipe in my compiler options so I am still hanging on around 5-7% too. That's still significant, but not as fun a number as the first one :-). I am coordinating one more patch set with Mike that makes sigprocmask and the core copyout function MP safe (so both copyin and copyout are MP safe). Copyout is basically MP safe already, sigprocmask needed only minor adjustments. Then I'm going to turn the code loose in 5.0 and, in a week or two, backport it to 4.0. Then it will be up to the rest of the community to push the MP lock further, I don't have as much time on my hands as I used to :-). -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
