Does anyone know why is that ? > Here is what ifconfig shows me : My axiom with regard to Ethernet is "Autodetect doesn't." I notice your connected cards are all showing 100/Full duplex. I suspect the other sides of your connections think they have negotiated half duplex. A duplex mismatch on 100BaseT will often end up giving you around 1-3 Mb/s actual throughput after all the packet collisions. Try using ifconfig to fix speeds on *both* ends of each connection to 100/FD, then see what happens to the throughput. The xl and fxp drivers are both very reasonable drivers/cards, so assuming your wiring is solidly connected cat 5, you should get great throughput. -- Clifton -- Clifton Royston -- cliftonr@tikitechnologies.com Tiki Technologies Lead Programmer/Software Architect "I'm gonna tell my son to grow up pretty as the grass is green And whip-smart as the English Channel's wide..." -- 'Whip-Smart', Liz Phair
