Gigabit LAN Upgrade

Not much time to post, so I’ll post the quick bandwidth test we did between two machines before and after the LAN upgrade:

Gigabit-Performance-Table-Fixed

Some notes:

  • For a bandwidth tester we used iperf, a linux script that has been ported to windows via a cygwyn build.
    • For Linux we just ran “yum install iperf”
    • For Windows we googled “iperf windows”, but here is one binary from UCF.
  • The real path just explains the connection between the two units.
  • The window size was automatically determined by iperf.
  • The 10 second test duration is iperf’s default.

And the same data graphically:

As you can see, there is considerable bandwidth improvement, even for the integrated NIC (and the PCI NIC is more than twice as fast as that!)
