You might be maxing out your server's PCI bus throughput, so it might be a b=
etter idea if you can get Ethernet NICs that are sitting at least on PCIe x8=
slots.
Leaving that aside, I take it you've configured some sort of CPU/PCI affinit=
y?
As for migration to another OS, I find FreeBSD better as a matter of network=
performance. The last time I checked OpenBSD was either lacking or was in t=
he early stages of multiple cores support.=
