If I get a quiet moment ,will hook cable directly to PC and unplug wireless router and see what sort of figures I get.

That must be a very subjective definition of "fastest" given BE offers 24 Mb download  :P

I don't know Virgin's infrastructure, but I imagine there will likely be some technical reason why you don't always max out speed.

 ;D Most of your phone based broadband  structures  suffer horribly during peak times, where speeds can be at 3Mb . Just had a talk with Virgin and now up to 16Mbs on recent tests. You will never get full potential but even BT came 5th to 8th on broadband scale. BE is not including  times when they too suffer. Its like anything else. these companies will promise you the earth on their broadband speeds,most for the average user never reach anywhere near  what they are supposed to be getting at 5-9PM.. Phone based broadband is not the way to go,unless you just want average speeds.
cheers

Huh, interesting statement there, because suffering during peak times has absolutely nothing to do with it being a phone based phone structure. Rather simply how well the company has implemented local loop unbundling and more importantly how much bandwidth they've given their local exchange, Virgin are just as likely to suffer from this if they have a high enough peak in an area they've not invested in well enough.

I've been on phone based broadband services that don't suffer at all during peak. The only big difference between fibre optics and copper is that you don't have to make nearly as many technical compromises with fibre optics, like you can have symmetrical connections again (which virgin don't implement :( ) you can get speeds up to 100 Mbps (which virgin don't implement :( ) and you can use them to travel much further distances from the exchange (which Virgin implement on a very limited basis :( ).

Exactly Quantum. Most of the Tech forums are filled with members wondering why their 8Mb broadband from the phone companies especially BT take a nose dive during peak periods. They are complaining that speeds have reached 800Kbs-3Mbs during tea time. You have got to remember that the phone companies are out there to sell an imaginary product, promising  so many Mbs on broadband when they know that they wll never come close to that figure.Even Virgin  will not reach full potential but they are not tied in to a phone line or a telephone exchange, and their speeds are more realistic with little or no slow down. IE when on the 10Mb broadband, was quite happy to achieve 6-8.5Mbs. and now at 16Mbs I am even happier. Virgin are now implementing a 200Mb instead of 100Mb which should come through shortly on their broadband service. Most of the phone companies are working off antiquated exchanges and indeed are trying to update to fibre optics. Common sense tells me that old copper wires have a limit with broadband, but even fibre optics as they are today will eventually reach an overload point. There are several new theorys out there as to how the internet and broadband might progress. You may see it but not me.
For now fibre optics win hands down.

200 Mb? I've not heard of this, I bet they're planning to achieve that speed by axing upload  :(. 100 MB, is 100 down, 100 up, perfect in my opinion!

Copper vs. optical is only about the wires to your home. The actual local exchange is not likely to be running on copper , so once you get to that point there's very little technical difference between virgin and random ISP x, there's only performance of implementation.

The big question is what to do about the internet back bone infrastructure. As it stands if large numbers of people started watching DVD quality shows on it on a regular basis, even with more modern compression techniques the internet would simply collapse under the weight of the required bandwidth.
