      My test configuration is 1 PC (bi-Athlon) with GigE card and 19
machine with 100Mb ethernet cards. The load on the GigE machine is 80%
and is running 38 process (19 in + 19 out) ...

     In an other message you were talking about a DMA benchmark. I have
am ASUS A7M266-D motherboard and I want to test its PCI capabilities....

    Thanks in advance.
