I've tested the Xeon CPU E5-1630v3 (3.70GHz, 4 core), myricom myx, intel ix and emulex oce cards, and the results under 5.8-current are great. OpenBSD 5.8 is not bad either. Under 5.8-current, a small routing table of 500 or so routes and option ART, plus PF NAT enabled and 1.4Gbps/200kpps of load, vlans, the average load is 11%, which transates to load of 30-40% on two cores and almost none on two (or sometimes evenly loads across three cores, out of nowhere). The network stack is undergoing big changes so this keeps improving. The oce card/driver gives me .06ms round-trip ping times across a cisco 5020 whereas ix and myx are currently at .2ms-.3ms rtt on the same switch. I'm not sure why, but it's fascinating. Chris
