How to increase downloading speed of utorrent

So here are few ways to enhanch the downloading speed of utorrent (my best)

When ever u click the torrent file for downloading let it start downloading now just open utorrent
right click the torrent that is downloading then goto Bandwidth Allocation select it to High.
Now again right click the torrent and goto Bandwidth allocation then goto Downloading limit and select Unlimited. Similarily repeat the above steps and goto Uploading speed and select it to Least value as possible. like 5kb/s or 3kb/s as low as possible.( i use 1kb/s)
Now after completing this again right click the torrent goto properties then now at below in Other settings untick Initial seeding, tick Peer Exchange option , tick Enable DTH, tick local peer discovery.
Now again go back to main screen of utorrent. Now goto Option in menu bar then goto Prefrences (shortcut is ctrl+p)
then goto Advanced on left pane now on right pane search for net.max_halfopen select it and change its value from 8 to some value between 80 - 150. ( i use 80) save the changes.
Now again goto Option in menu bar then goto Prefrences now goto connection on right pane
Tick the boxes saying Add Window Firewall exception, Enable UPnP porting mapping, Enable NAT-PMP port mapping.
One more thing keep in mind that whenever a new version is available update ur utorrent. Getting the latest version of Utorrent client might help you to fix slow download speed by bypassing the technology using some hacks like protocol encryption. You need to do a trial and error to determine which version works best for you.
Here is list of trackers that u can add to ur torrents. Right-Click on the torrent which is very slow and go to Properties. Then under the General tab, at below side there will be tab Trackers you’ll notice a list of existing trackers for the selected torrent. Right click and select Add tracker & then paste the list given below as it is with empty line between 2 links.
