Hello List !

After my windows 2003 Server setup under XEN 3.0.3-testing (Changeset
11636) I was interested in network performance. Windows 2003 Server runs
fine and feels fast but network performance (measured with netio) is
really bad.

I only reach about 5-6 MB/s while the I/O load in DOM0 is high, even if
I measure Dom0 to HVM communication with no physical network involved.

Is there any way of increasing network performance for HVM guest ?

I sometimes heard about "paravirtualized drivers"...
