Hmm, I'm rereading the product description for the Soekris lan1621, which would go into my 4801's PCI slot and give me 2 enet ports. It claims 'High performance PCI busmaster interface with large buffers and interrupt holdoff'. Would you have higher hopes for this than the on-board enet ports? Do you know whether the OpenBSD 4.0 sis driver would support the interrupt holdoff feature?
Has anyone on this list actually tried a lan1621 on a Soekris 4801 in an effort to boost performance, and were you satisfied with the results?
