Yes.. Speedtest.Net is not really good now since I found out that many providers purposely CLAMP DOWN on the SPEED TEST SERVER CONNECTIONS.
Singtel played punk and restrict OUTSIDE NETWORK CONNECTIONS to 2 pipes per session.
I am now adding the IPv6 Compliant Speed Test and for IPv4 ..try the BBQ Speedtest @
This is more real than Singtel or SPEEDTEST.NET
Mainly because they are not allowing Gigabit connections and multiple simultaneous connections to the port at the end server side.
