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.
