Identical network cards for Win2k, Linux SMP and OpemBSD processor (Intel Pro 100). Linux was run on dual p3/1Ghz(SMP), Pentium2/400Mhz and P3/800Mhz (UP). Windows 2000 was run on p3/1Ghz UP. I've made tests with same results against Linux UP boxes running on Celeron/600 with 3com Vortex and realtek 8139 NICs. I've outlined that the result is the same no matter if you hit via 1Gbit or 100Mbit.
Could you test the pro100 adapter with the intel e100 driver with cpu-saver enabled (insmod e100.o ucode=1) ? (Also playing around with other parameters like IntDelay, BundleMax and Tx/RxDescriptors might make a difference). The 'cpu-saver' option should limit the number of interrupts the nic generates (this might help if the interrupts bring the machine to halt) (read the e100 driver manual for more information). -Jarno -- Jarno Huuskonen <Jarno.Huuskonen () uku fi>
