Nikola, thank you so much for your response! It kind of looks that way, and we do have another candidate machine that has a PCIe 3 x8. First thing, I never liked riser card and the candidate IBM x3250 M$ does use them. Not sure how much of a hit I will take for that. Secondly are there any proven intel 4 port cards in PCIe 3 preferably pro 1000. > Leaving that aside, I take it you've configured some sort of CPU/PCI > affinity? For interrupts we disabled CONFIG_HOTPLUG_CPU in the kernel, and assigned interrupts to the less used core using APIC. I am not sure if there is anything more we can do? > As for migration to another OS, I find FreeBSD better as a matter of network > performance.

I know I mentioned migration, but gentoo has been really good to us, and we grew really fond of her :). Hope I can tune it further before retiring it as our OS of choice. Nick.
