I just compiled the drivers into the kernel.
The only way to really measure the speed of the cards (and not of hard disk, nfs-subsystem etc) is to send _huge_ amounts of data really, really fast. Personally I like netcat (it´s debianized) for that sort of stuff, just dd if=/dev/null | netcat 1.2.3.4 and, on the other side netcat -listen >/dev/null (I´m not sure about the exact synta, but it´s easy enough). >am I forgetting to set something ?

If the cards are autosensing there´s a good possibility that they negotiated 10 mbit/s, most cards come with a DOS-driver where you can explicitly set spped&duplex (they memorize that, so you need only do it once). cheers, &rw -- / Ing.
