there is extra factors on speedtest.net

it goes via flash which adds significant cpu requirements.
also VMs peering is dodgy and could be affecting some speedtests, certianly namesco is capable of far higher than 100mbit as I have tested it with servers hitting 700mbit/sec.
rWIN may also affect it although with it been 4 threads I wouldnt expect it to have a significant effect on the 10mbit service. On old operating systems tho it can easily affect it on any other tier.

As a rule of thumb if things feel laggy/broken or my net has been dodgy anyway I will do a speedtest on speedtest.net.
If the test is slow I will then see if it gets backed up by manual downloading (usually of multi gigE servers I run). 95% of the time its accurate, occasionally its not and thats usually down to VM peering or core network issues.
