The problem is: You need buses that support the bandwith. As I know the
limitig factor on this test setup was the bus throughput of the
machines. A PPro 150 may have a 33 MHz 32 bit PCI bus, that is saturated
with a single 1 GBit/s connection. To feed a 10 GBit/s pipe you need
PCI-X 64/133 or some funky custom interface like e.g. the I/O links in a
big SGI Origin 3000. AFAIK this links (you can have dozens in one
machine) are capable of 1.6 GByte/s fullduplex.=20
