Hi midiw
If you can get a speed test to a major server near you that includes upload speed, like those offered by
http://www.dslreports.com/stest , you can tune your Pro's speed settings for optimal results.
For example, if you can achieve >90 KB/s upload speed, then you can set your speed as a T3, which allows you to set the upload speed settings at the minimum allowed for a T3. This would mean a swarmed download with Pro *could* download from 14 sources.
cheers.
