i built netperf for my n800 the other day, and tcp performance was pretty miserable. from memory, it was able to send at 4Mb/s, but wouldn't receive more than about 0.5Mb/s from any other host. by contrast, my big ubuntu box was able to cram 925Mb/s into my MacBook Pro, although obviously not over wifi. My NSLU2, running debian, was able to send at 64Mb/s over 100-BT.
