IPerf Network Testing
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 (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.
