I'm sorry but that doesnt make any sense to me. your computer is not too fast for your internet service... your internet service might be just plain too slow.

uh! tell me about your internet service! are you wireless? is it DSL? is it cable? whats your mom's middle name?

if i had to take a shot in the dark (which I do) i'd say get better internet service or at least a service call so they can tell you if anything is wrong.
