Hi Chris,
did you include the full duplex kernel patch as mentioned here:

Nope, I had entirely forgotten about that.

Could I ask for some input from anyone involved - how come full duplex is producing better results, when we know that the MVP has small network buffers, and that full duplex was specifically disabled for the MVP for that very reason?

Lutz

As TheAlamo stated in the old threat, an ifconfig returnes "DMA chan:1"; maybe thats the more important trick of the patch... but its just a guess...

In every case a networkcard should handle out a full duplex mode. If this is not possible, then it come to half duplex and so on.
In my homenetwork(100MBIT LAN) every other devices, have an fullduplex connection. So why not the mvp? Is this a buggy driver or card? Theoroetic has an full Duplex connection the doubled speed, as it can send and receive 100MBIT at the same time(200MBIT).
As I can see, the mvp have much collisions with half duplex, and with full duplex it is gone. Tested with amount of 4GB received data.
For me this result is better. For anyone who wants to test this too, I have made a dongle for it.
