Has anyone elsed a general slowdown in downloads???

When I first downloaded Limewire, I would find files from people with T-3's and get SICK d/l speeds (over my Cable modem).

Now, I am experiening horribly slow d/l times. Like 1 or 2 Kbs.
What gives?

It's not my connection, I still pull 800-900 K when the source can feed it to me that fast. And it's not like I am d/l popular movies and crap, I mean anything I try is SLOW!!!

Anyone have any ideas on this?
