Hi all, slowly crawling through the mails.

We are using MSI, /proc/interrupts look like:

(sorry for the line break).

What we don't understand is why only core0 gets the interrupts, since 
the affinity is set to f:
# cat /proc/irq/378/smp_affinity
f

Right now, irqbalance is not running, though I can give it shot if 
people think this will make a difference.

> I would suggest you try TCP_RR with a command line something like this:
> netperf -t TCP_RR -H <hostname> -C -c -- -b 4 -r 64K

I did that and the results can be found here:
https://n0.aei.uni-hannover.de/wiki/index.php/NetworkTest

The results with netperf running like
netperf -t TCP_STREAM -H <host> -l 20
can be found here:
https://n0.aei.uni-hannover.de/wiki/index.php/NetworkTestNetperf1

I reran the tests with
netperf -t <test> -H <host> -l 20 -c -C
or in the case of TCP_RR with the suggested burst settings -b 4 -r 64k

On the web page you'll see that there are about 4000 interrupts/s for 
most tests and up to 20,000/s for the TCP_RR test. Shall I change the 
throttle rate?
