i have a premium rapidshare account and i'm dl'ing something that is 250 parts and 40gb....right now i have the max dl set to 20...the speedometer at the top is at 600kb/s but my files are only going at like 30-50kbs...if i lower max dl's, will my dl speeds get close to 600kbs? also my files keep losing connection...is this because too many files are going at once?
