I installed the NIC to the shared PCI slot and it has helped, but not as

across two NICs, which makes me wonder the max throughput I can expect
on a firewall on these Intel boxes.
What is that in packets per second ?
Ingress is 16255 packets/sec and egress is 18032 packets/sec.
16k+18k pps at 70% interrupt cpu ? On a modern PC ?
That sounds disapointing to say the least.
I checked one of my ancient 600Mhz P3 with a four port dc, it's doing 15k+15k
at 33% interrupt cpu. I dug through old emails and found that an old firewall
I had with Athlon850MHz and one ti (netgear) doing 26k+26k on it's vlan trunk
at 15% interrupt cpu.
Please tell me your box is an old piece of junk like my boxes.
Nope-- it's a Supermicro 6023P-8
(http://supermicro.com/products/system/2U/6023/SYS-6023P-8.cfm). Intel
Xeon 2.4, 533mhz bus, onboard dual Intel 82546EB gige nics, 133mhz
PCI-X, etc. etc. I'm running a snapshot from June 3 and as far as I can
tell, apm is not enabled (did a dmesg|grep apm).
