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%.
