Hi Adalbert,

Hi everyone,
I've got a problem with my DomUs. When I upload files to a DomU, I can
use my full bandwidth but when I try to download something from it,
I've got only about 30kB/s or even less. I'm in the same LAN so it
should be something in the MB/s range.

This sounds very familiar to a problem I had with my Ubuntu Hardy DomUs. You might want to try this command:

ethtool -K eth0 tx off

***********************************************
You disable checksums offloading at DomUs ?

Hope this helps,

Paul.

Why can't a programmer tell the difference between Halloween and Christmas?
Because OCT31 = DEC25.
