If not, what quality of hub/switch are they connected to? Your 700-800kbps seems a little slow in the first place for 10Mb ethernet, even using some of the cheapest cards on the market. I use primarily the Netgear FA310TX and Intel fxp cards, and get much higher rates, even at 10Mb -- 100Mb obviously goes a whole lot faster. This kind of problem is often caused by the auto-negotiation of speed & duplex settings between the card & the "other end" - hub, switch, another card, whatever. I've run into problems where the auto-neg results in <1Kb/sec transfer rates - manually specifying the parameters fixed these machines. A little more about your network setup and some sections of your dmesg output would be helpful. --mike - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Understated/funny man-page sentence of the current time period: From route(4) on FreeBSD-3.4, DESCRIPTION section: "FreeBSD provides some packet routing facilities." ...duh.......
