Hi all,
cpuset is the command to set a cpu affinity,
there are details @ http://bramp.net/blog/post
vmstat -z is the command you need to determine whether there is contention
for mbufs.
although the cpu usage does not suggest the system is memory constrained.

Hi Fabizio,
Ignore my last mail direct to you, 638976 PPS is awful.
(today is a national holiday here, my brain is not switched on).
To me it looks like interrupt coalescing is not switched on for some reason.
Are you passing any parameters to the driver in boot.conf.
Could you retest with vmstat

Hi,
The limitation that you
If you go to FreeBSD 8 you will get the improved stack code, and the RX/TX
queue pairs
will be pinned to cpus. It should improve performance.
Make sure you have enough mbuf memory allocated, try increasing the
descriptors.

Hi,
The limitation that you see is about the max number of packets that
FreeBSD can handle - it looks like your best performance is reached at
64 byte packets?
Am I correct that the maximum you can reach is around 639,000 packets
per second?
Also you are not routing the traffic, but instead
Hi all
I am doing some tests on a BSD system with a 10gbe Intel based network card and
I have some doubts about the configuration since the performance I am
experiencing looks (very) poor.
This is the system I am doing test on:
