test vpn bandwidth and speed with iperf

This article explains how to use a free utility called iPerf to test the speed of a VPN connection. In this example I am running iPerf on windows but there are other versions available (i.e. Linux). Download iPerf from  http://linhost.info/2010/02/iperf-on-windows/ Put a copy on 2 computers with 1 either side of the VPN.
