Hi Jeff,

I tried your patch. Ran a buildkernel, timed. Recompiled kernel including
your patch, rebooted and reran. Please find results below.

w/o patch
hulk# time make -j8 buildkernel
837.808u 138.167s 10:28.96 155.1%       6349+1349k 2873+7780io 303pf+0w

w patch
hulk# time make -j8 buildkernel
838.554u 168.316s 10:52.10 154.4%       6263+1332k 6489+7791io 11pf+0w

I only understand the 10:52 seconds thing, but it looks like it's
stressing less and still getting things done.

System is AMD Athlon X264 2.2Ghz

Kernel is GENERIC.
hulk# uname -a
FreeBSD hulk.superhero.nl 7.0-BETA2 FreeBSD 7.0-BETA2 #0: Sun Nov  4
20:30:23 UTC 2007     root@hulk.superhero.nl:/usr/obj/usr/src/sys/GENERIC 
amd64

I see you have a new patch. Could you send that to me? When I download it
from the mailman site I get weird characters in the downloaded file :(

Cheers

Patrick
