Nope; still having problems with single thread downloads.
Typically getting around 11Mbps (even at gone midnight) on single thread downloads of the TBB test files.
TBBmeter is giving similar results (even in multi-thread mode - the only way I can max out my connection is using Usenet or a download manager).
Speedtest.net (and the flash based speedtesters) are giving results similar to my line speed (around 77Mbps down / 17Mbps up), TBB speedtester is giving less than 40Mbps down and only around 6Mbps up.
So, once again, either BT seem to be throttling single thread downloads or something's awry with TBB tools or their links to BT (or BT are throttling the TBB speedtester protocol/port).
