Help!

I have a fileom.com premium account and it shows speeds up to 20 MB/s. I have at&t U-verse. Is there anyway to possibly speed this up?

 

Open more connections, try 3 at 1st depending if it lags then try maybe 5 or 8

 

What do you mean by open more connections? As in proxies or as in start more downloads with Jdownloader?
