Re: Q from the US
"to the extent that my BT client, when getting ISOs etc, often reports as 10MB/sec transfer rate - that is, I'm not having any problems saturating the true bandwidth of the line. You just don't get that on consumer xDSL or cable"
Virgin Media 100Mbps connection and I'd count this as a slower period. It's very region dependent though with some older cable areas not as good as others. I've never had a problem with speed though and regularly get what is advertised although the upload has yet to be upgraded to 10Mb so it's hovering around 6Mb still.
