Here are some tricks to increase your uTorrent speed to up to 80%!!
Just follow the following simple steps 
For connection setting I checked Enable UPnP port mapping, Enable NAT-PMP port mapping and i use 4568 as my Random port.
Checked Use additional upload slots if upload speed <90% and follow the value setting as indicated at the screenshot above.
Checked for Enable DHT Network, Enable DHT for new torrents, Enable Local Peer Discovery, Ask tracker for scrape information, Enable Peer Change, Allow incoming legacy connections and Enable Outgoing protocol encryption.
Edit net.max_halfopen and change its default Value to 90
Done!!
You can now test your iTorrent download speed.
Another tips is that even though the uTorrent speed is increased, it is important for your torrent file to have a healthy number of seeder too. Just bear that in mind. Enjoy!!
