I'm curious whether Robert's patch might have an
effect on samba3 performance as well.
This isn't very methodical, but I see about
60% increase samba3 read bandwidth (from 14MB/s to
26Mb/s) when changing from the default
kern.timecounter.hardware=i8254 to TSC, which
makes me wonder whether it might.
Below are details..

-------------------------------
Server: Samba3 on a dual xeon running FreeBSD 6.0 release.
Client: nbench on windows XP SP2.
Client and server are using intel pro 1000MT gigabit cards.
Here's the nbench output w/comments:
w/sysctl kern.timecounter.hardware=TSC:
Disk Performance, MBytes/sec
File size: 100.0 MBytes
thread: 0
write: 7.93
read: 22.94
followed by kern.timecounter.hardware=i8254:
Disk Performance, MBytes/sec
File size: 100.0 MBytes
thread: 0
write: 6.80
read: 14.01
and back to kern.timecounter.hardware=TSC:
Disk Performance, MBytes/sec
File size: 100.0 MBytes
thread: 0
write: 7.77
read: 23.61
