I would suggest running Tor in a normal console window (not a service)
and seeing what log messages pop up when the slowdown occurs.

Optionally, you can dig through torrc (which is not included in the
Windows install by default) to find the appropriate option, or use a
controller like Vidalia to adjust the configuration so as to view the
log data.

I suppose I'm just registered to a different list, but they are
probably cross-posted appropriately.
