With the new TCP/IP stack replacement and major updates to the em

saw a cvs commit for em a little while ago saying the new em driver
can achieve higher transfer rates then using em with polling enabled.

I'm curious whether Robert's patch might have an

No real difference here, tried ACPI-fast, i8254, and TSC. :( My
transfers still average at 10MB/s (although it did peak at 20MB/s once)
Which is really horrible for a em gigabit link with jumbo frames
enabled. The performance of Samba on FreeBSD just stinks, for unknown
No real difference here too...
I started a thread on that subject not long ago and following Robert's
tip setting net.inet.tcp.inflight.enable=0 yielded better results.
Hopefully this stuff will make it into 6.1-Release
I'm using both polling on the em interfaces
and net.inet.tcp.inflight.enable=0 w/6.0 release.
Without these, I still see a a repeatable
10% or so increase when switching
from i8254 to TSC timecounter.
