Over the last few days I have been getting these very poor test results from the TBB tool.
However, Speedtest.net results are full speed i.e. 150Mbps down and 10 Mbps up.
The Which speed test is almost identical to the Speedtest.net results.
Performance on my PC seems pretty normal and I can stream HD from the iPlayer without problem. The results above are from tests taken just after 8pm. I have tried the TBB test during off-peak times with no change.
What would account for the discrepancies, I wonder? Thanks for any explanation.
