Well, this is obvious...

IIRC the way it works is by splitting the file that is being downloaded into very small parts and then combining them together again. Scanning this will be very CPU intensive.

It's more about how p2p/utorrent works...
But here some suggestions, that might help you speed things up.
1. reduce the concurrent number of downloads with utorrent.
2. expand the ram on your system - to at least 1gb, better more!!
3. or just disable the p2p shield - be sure to scan all downloaded files on demand, if you do so.

I had a chance to download 1GB of data via uTorrent about a month ago, but I didn't see such overload....

Try to disable Heuristics in P2P shield expert settings -> Sensitivity , and make sure "Test whole files" unchecked.
Does these settings change your issue?
