Chris,
I've only seen it peak at about 80 MB/s but only when imaging. The Xserve was plugged into a 1 Gig port but clients are at 100. Don't know about maximums.

We have our main xserve NIC's 'Teamed' or rather using Link Aggregation.
And we are seeing upwards of 120 MB/sec. It did take configuring the Switch
as well as setting up the link aggregation on the server. I attached a
screenshot of the Network Graph when it was doing near that. This was
during some peak imaging times for us. I think we were pushing the server
a little hard. ;)

Keep in mind that there are a lot of factors when measuring performance...what else the server(s) and client(s) are doing, their respective hardware (drive speed, network speed, cable integrity, available RAM), and software (what is running and eating cycles).

Of course, there is the network - many networks analyze traffic, capture packets, shape traffic, run analysis and remote checking, and any number of things which may adversely affect network performance. And, of course, there are switches...some support port trunking (link aggregation) while some don't - some have higher latency depending on configuration, some using management software may have *interesting* configurations.

In short - talk to the network admin, talk to the sys admin (if you aren't them), and run tests.

If your network is up to it, you can can always add more bandwidth.......:
