Is that the Cirrus ep93xx? If yes, then you're only getting 3 MB/s because the ethernet MAC is lame and the machine is running out of CPU because it needs to copy and checksum every packet in software -- if you'll profile it you'll see that it spends most of its time copying stuff around, and the TCP overhead is minor in comparison. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
