Something is wrong with Virgin Media's speed test software.
Repeatedly, I am getting an over-egged upstream speed test result with the VM/Speedtest.net software. My upstream provision is still for just over 22Mb, with only 2 bonded upstream channels, but my results are often over 30Mb. My downstream is as expected.

My results at speedtest.net and dslreports results are just over 21Mb.
It is worth noting that during the software-based test, the upstream test bursts at 150Mb. I have loads of processor resources i5 3.3GHz with only 9.9% being used during the test. At the same time the network speed registers at 21.3Mbps. (task manager)
