As mentioned=2C there is a limitation to TCP-based speed tests - TCP throug=
hput is very sensitive to packet losses=2C particularly during slow-start=
=2C in addition to requiring end-host tuning (as an exercise=2C try running=
 speedtest.net on a high bandwidth connection). You could use something cal=
led "available bandwidth"=2C which is kind of like the "leftover capacity" =
on your path - I've been using this tool called pathload2: http://www.measu=
