How strange - Im still seeing circa 10Mb - yet by evening its normally ok and I can get full speed.
I'll test again later tonight.
Edit to add
---------------
Interesting - the more connections the faster the speeds.... hmmmmm.
Results shown on DUmeter whilst downloading via grabit.
You can see a distinct difference in speeds depending on no of threads open.
One thread = 10 mbps (circa)
Two threads = 16 mbps (circa)
Three threads on usenet = 21 mbps
Four threads on usenet = Maxing out line and this PC starts to struggle processing it quick enough
