I used the smbclient program to copy a large file from a win95 machine to the FreeBSD machine. This utility tells you the average throughput when it's done copying. I get around 500kb/sec. Apparently, this is close to the theoretical maximum for 10baseT. I suppose _any_ 10baseT card should be able to manage this (they are all 10Mbit/sec), though I suspect the 'slower' cards such as the NE2000 are slower because they use more CPU overhead due to the increased IRQ rate. The raw throughput for any 10baseT should be the same (in my opinion). Can anyone else comment/correct me on this?
