Im a Bitcomet user before and now fully switched to utorrent. Utorrent maximize my download speed as well as my upload speed. I was a leecher before because Bitcomet cant maximize my upload speed even if i stay online for a long time. Utorrent is a very small program yet very powerful unlike other bittorent clients ive tried before they slow down my system. Its also amazing that utorrent has a speed test which configure itself for its best performance that other bittorrent clients doesnt have.
