Iperf was orginally developed by NLANR/DAST as a modern alternative for measuring maximum TCP and UDP bandwidth performance. Iperf allows the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss.

Latest Version Notes:

  • iperf - iperf.exe and html docs (iperf version 2.0.5)
  • jperf - java gui for iperf (includes jperf GUI version 2.0.2 & iperf 1.7.0)
  • kperf_setup.exe (includes jperf GUI version 1.0 & iperf 2.0.2). Installed progam (includes start menu items) into c:\program files\iperf-2.0.2\

Tests For WANs where compression is used, use a non-compressible test file such as a large .jpg.
