This is probably the limit of the hardware disk drive and the chipset.... you said a T42? it's still IDE not SATA.... and even a 3GB/s SATA may only have a sustained throughput of 200mbps without raid arrays.

Hi again...

10MBs = 80Mbps, which is good, considering the transfer overhead. That said, when testing gigabit adapters, I've found that I really need to test them at gigabit widths (speeds, for those lurkers who think along those lines, though "speed" is more accurately a measurement of latency - or vice-versa). When Doug & I were futzing about with the Broadcom drivers, we tested via a gigabit switch as well as via CAT-6 crossover (which gives an indication of how much bandwidth is lost in switching overhead). We used netio, BTW.

Interesting; thanks. Maybe we'll (I'll) have a chance to do some measurements at Warpstock this weekend. Wired or not, I'll post some results if I do. ;-)
