Hi all, slowly crawling through the mails.

As asked in LKML thread, please post the exact netperf command used
to start the client/server, whether or not you're using irqbalanced
(aka irqbalance) and what cat /proc/interrupts looks like (you ARE
using MSI, right?)
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
Yes, InterruptThrottleRate=8000 means there will be no more than 8000
ints/second from that adapter, and if interrupts are generated faster
than that they are "aggregated."
Interestingly since you are interested in ultra low latency, and may be
willing to give up some cpu for it during bulk transfers you should try
InterruptThrottleRate=1 (can generate up to 70000 ints/s)
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?
just for completeness can you post the dump of ethtool -e eth0 and
lspci -vvv?
Yup, we'll give that info also.
