I'd be interested in some of your thoughts if I may.
I've seen various instances of the BT Speedtester reporting faster speeds (throughput) than others over the last few months. For example, around 3pm yesterday, my RIN (PlusNet) connection was reporting throughput of 5Mbps, whilst all other http sites were reporting 2-3Mbps.
Do people on other ISPs see this? Does anyone have an explanation? I'm just wondering if the BT Speedtester reports the maximum throughput gained during the test, rather than the average, which it claims to do and I'd imagine all other testers do.
