Saturate a ethernet card is easy.
The kernel translation to user mode, packet handling, sending back to
kernel stack, network layer
tooks a big path and involve a lots of context / cpu execution mode (ring0
- kernel, ring3 - user) switches,
and this affects directly your latency, stability and
Oh I know that's not very fast, but this is an endurance test, not a
throughput test. I want to see that latency does not rise over a long
period run. If you try for maximum throughput, you mess up latency and
then you can't see if something is changing slowly over time.

Test ran was on 2011, current HW should be at least 2 / 3 times better...
* The test has now passed 220,000 seconds (2.5 days) with no failure. 1000

* Average response time is not changing. It has been between 1 and 2 msec
the whole test.
* Router memory does *not* appear to be growing without bo
