| I would suggest that you test with an ethernet cable directly connected between the 2 Mac servers (you do not have to worry about a crossover cable, a Mac will reset it's interface to accommodate). Just give each machine a different fixed IP address on the same subnet. Try pinging between the 2 machines to ensure you are connected. You can check how the interfaces settings have been negotiated using ifconfig. Then try iperf. I have not noticed issues on OSX as long as one has a pretty capable machine (G4 or G5) and you are not running many other applications on the machine. To really have iperf run well on OSX, reboot the machine into single user mode (console mode) - hold down the "s" key when rebooting. This will boot the machine with no visual interface, just a terminal console. Now run iperf from the console.

So far the readings suggest that things are looking pretty grim over here. For example, running iperf on a Mac OSX server, connected to a Gigabit switch to another Mac OSX server, connected to Gigabit as well:
