Hi,
This is really interesting work! Reading the pdf file, it
seems forwarding performance on 6 and 7 is still much lower than
RELENG_4 ? is that correct ?
---Mike
Thanks,
Yes it is still slower but as you can see in the graph (programming
cost) just adding a mutex
drop the rate and we have some on the forwarding path.
We have beaten FreeBSD 4.x with pollng on 2 core with the best
throughput at 7089Mb/s
but only when the test last 10s => maybe periodic task that get some
CPU time.
One really interesting things is that FreeBSD 7.x can have great
performance:
It performs slower than FreeBSD 6.x when using one CPU (4437 vs 5017)
but
better when using 2 CPU (5214 vs 5026).
While reading the pdf i've discovered a mistake in the loss
percentage: it is 0.001% and not 0.0001%.

You can find a summary of all my tests and the source code at the

Feel free to ask more detailed information if necessary and report
any bugs / comments.
