PCI-64: how to find

I am currently evaluating an Intel Pro/1000 fiber in a PCI 64/66
The information about PCI 64/66 is found in the driver info:
Description Intel(R) PRO/1000 Network Connection
I have tested bandwidth with ttcp talking to 19 100Mb/s machine and
got 930 Mbit/s bandwidth in either direction.
I am currently having problem with fullduplex; the driver and my
switch are telling fullduplex, but doing ttcp in both direction
simultaneously gives only 520Mbit/s in both direction (a total of
1040Mbit were I expect 1800Mbit).
Is there (objective) comparison chart (bandwidth + latency) of
Gigabit ethernet vs Myrinet vs Dolphin ?
Thanks in advance.
