Is there a method of measuring the effect of changes on the throughput of individual programs? For example when downloading data from Newsgroups I can alter the number of connections from 1 to 10 (I think) but the more I add above a certain level I get no increase in speed. Sygate firewall shows incoming speed at about 70k. I'm not sure that this is showing an accurate figure.

I guess I want to know how I can accurately measure the throughput of any program at a given time plus the overall throughput so I can see the effect of having 2 progs downloading at the same time.

Optimisation of downloads was the phrase I was looking for..........
