I think this depends from your ethernet card. If you've got a PIO-only card (NE2000, 3C590 etc.), CPU speed might be important. For a shared-mem or DMA card (SMC8013, DEC-based PCI, Lance), the CPU speed is probably much less important. Yes, i know, the 3C590 could in theory also do DMA, but even the tech-doc from 3Com makes you cautious about not assuming that this will overally get you better performance. It's very hard to draw the line for this card where DMA makes sense and where not. I think the days where 3Com was leading in networking hardware are over now. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
