Varying, Erratic Download Speeds

[PhilJack]

Hi,

Yesterday and today I noticed my download speeds have been changing dramatically. For instance I downloaded something this afternoon and it was going at 150 kb/s, as it had about 200 seeds.

So out of interest I downloaded the exact same thing about an hour ago and it is going at 15 kb/s. It still has the same amount of seeds, so why is it going so much slower than this afternoon?

This is happening with a lot of my downloads, the speed is changing so much from time to time. It isn't just utorrent, the same thing has been happening with my Limewire at exactly the same time the problem with utorrent has been occuring. The Speeds drop at the same time on both applications.

Any help would be greatly appreciated.
