Thanks Fabion for that. After increasing my hosts the D/L speed stayed at a higher constant rate but, as always, if I am D/L say 2 different files it will take the bandwidth from the first D/L and split it with the second.
Why ? This does'nt make sense to me as I have a 512 adsl connection and the sources are from different people so I should in thoery be getting a much higher speed.

Am I seeing this from the wrong perspective ?
