  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. In this example I have put in the c:\triangle folder     On the “server” PC open a cmd prompt and navigate to the folder containing iperf. Note on computers running Win7 or Win2008 I recommend running the cmd prompt in elevated mode.   Run the command  iperf –s         On the “client” PC open a cmd prompt and again navigate to the folder containing iperf.   Run the command  iperf –c          After a short while the estimated bandwidth is displayed.
