Depens on the harware.
 We got 750 mbits on a single box with a 2 channel intel gigabit card
(Intel PRO/1000 MT Dual Port (64bit/66MHZ PCI) in a Fujits-Siemens PRIMERGY L200 with 2 Intel PIII (1.40 GHZ) and 2 GB SDRAM.


The important fact is the "(64bit/66MHZ PCI)" part - as standard PCI
(32bit@33MHz) will not transfer much more than 1Gbit/s. So two Gbit/s
cards on the same Standard PCI bus would only let ~500Mbit/s pass
(half-duplex). Even the fast+wide PCI barely is just fast enough for a
full Gbit/s line run full-duplex.

that's right :-)
