Correct me if i'm wrong, but this program has little to do with download and upload speed. Unless you haven't checked the MAX option in preferences, it's most likely just the network being slow. And anyway, the feature i like most, is that it CONSTANTLY downloads the file until it is completed, which is an awesome feature considering that MOST files i've tried to download, ecspecially large movie files, either get cut off or time out. With xolox, you just select the file you want, and wait until completes, no worries. Just be patient....
