My guess is that 32MB is not enough to hold a full routing table, or maybe
if I was running NOTHING else... From my calculations, 48MB would probably
be okay, but memory is cheap as dirt right now, so...

No, it's the old N2/ISA card. I obviously would love to get full throughput
on all of the ports if it's possible.. I am noticing a MAX of about ~250KBytes
a second from ethernet -> ethernet right now...

Um, well.. There is only 2 PCI, 2 ISA, 1 VLB, and 1 shared/ISA-PCI slot..
ISA(4) = 1 Video, 1 N2 card, 2 SMC Elita Ultra cards
Which leaves 2 usuable PCI slots = 2 Intel ethernet cards... ;)
A little more info, here is the basic outline right now... What is needed
to get more interrupts/second? How can I tell if I'm maxing them out/
