The tests I reported where on UP systems. Perhaps the default settings are better for this in 2.4, since that is what I used, and you used your hacks for both.
My modifications to the kernel are unlikely to speed anything up, and probably will slow things down ever so slightly. I can try with a UP kernel, but my machine at least has a single processor. I'm using the SMP kernel to take advantage of HT.
Are you getting drops or overruns (or both)? I would assume drops is a decision to drop rather than an overrun which is a ring overrun. Overruns would imply more about performance than tuning, I'd think.
I was seeing lots of NIC errors...in fact, it was showing a great many more errors than packets sent to it, so I just ignored them. I increased the TxDescriptors and RxDescriptors and that helped a little. Increasing the transmit queue for the NIC to 2000 also helped a little.
I wouldn't think that HT would be appropriate for this sort of setup...?
2.6.11 seems to be faster when running SMP kernel on this system.
You're using a dual PCI-X NIC rather than the onboard ports? Supermicro runs their onboard
Of course. Never found a motherboard yet with decent built-in NICs. The built-ins on this board are tg3 and they must be on a slow bus, because they cannot go faster than about 700Mbps (using big pkts). I'll benchmark things again when 2.6.13 comes out and try to get some more detailed numbers...
