With any file sharing program, your speeds are limited by:
1. Your bandwidth
2. The bandwidth of the machine you're downloading from
3. How many simultaneous downloads and uploads you have going (each uses some bandwidth)
4. How many simultaneous downloads and uploads the other guy has going
You can only control your end of things. There's good information on optimal settings for Bitcomet on
this page and an index to the site on
this page.
