Deliberately evading the language filter is never a good idea.

Well it gives the little 'Tin Hitlers' a chance to throw their weight around.

'On long lines it is not uncommon to see an increase in connection speed during the colder winter months followed by a drop as it gets warmer again. That is what I was thinking you might have been experiencing.'

The copper expanding and contracting.....

Hmmmm. So that shortens it, but as electrical current flows along the circumference of cable the resistance increases when cold. Discuss.

getting a constant speed day and night over christmas, no real change in sync.

You have to resync to see a change. Maybe SNR has risen?

Well Billy boy, I simply will not be talked down to or abused by ANYBODY, agreement or no agreement. I initially treat others as I would wish to be treated, from then on as they deserve. The problem with forums, is that they are predominately frequented with snotty-nosed know-it-all anoraks, each convinced that their view is the only correct one.

True.

That's coz you have a rubbish ISP, nothing to do with TB.

Select port 80 and you might get a better (higher) result but will be representative of web/http traffic not other types.

I used to think that until seb corrected me. Selecting port 80 on the tbb speed test does not invoke http protocol.

Actually it isn't necessarily as simple as that even.

It all depends on how shaping/throttling/prioritisation is being done. If they do it by protocol then selecting port 80 will make no difference. If they do it by port then it could make a big difference (irrespective of the protocol actually used).

It depends on what equipment is in use and how it is configured.

I always thought that it was just RF currents that flow on the surface hence copper wire is silver plated to improve conductivity at high frequencies.

In the case under discussion, the diameter of the copper will reduce when cold along with the circumference hence the signal will not have so far to travel and get to its destination faster

It's also plain wrong as resistance increases with temperature rather than decreasing with most materials (including copper).

http://en.wikipedia.org/wiki/Temperature_coefficient

A negative temperature coefficient (NTC) occurs when the thermal conductivity of a material rises with increasing temperature, typically in a defined temperature range. For most materials, the thermal conductivity will decrease with increasing temperature.
