With 1CPU-SMP-HT I'm on UP level of performance this with forwarding two single flows evenly distributes between CPU's. So HT payed the SMP cost so to say.
Also I tested the MB bandwidth with new threaded version of pktgen just TX'ing a packets on 6 GIGE I'm seeing almost 6 Gbit/s TX'ed w 1500 bytes packets.
I have problem populating all slots w. GIGE NIC's. WoL (Wake on Lan) this is a real pain... Seems like my adapters needs a standby current 0.8A and most Power Supplies gives 2.0A for this. (Number come from SuperMicro). So booting fails radomlingy. You have 8 NIC's -- Didn't you have problem?
Anyway I'll guess profiling is needed?
