Increase the speed of torrent file download with utorrent... by optimizing the settings..

Pls visit my previous post for basic idea about the bittorrent file sharing @ http://new-kerala.blogspot.com/2007/07/basic-knowledge-about-torrent-file.html


Note: The settings are based on 256kbps broadband internet connection and uTorrent 1.7 version (which I'm using.. :). Pls make proportionate changes according to your internet speed.



First go to Options>Preferences>Downloads


Under Other Settings,



1. Append .!ut to incomplete files: UNCHECKED


2. Pre-allocate all files: CHECKED


3. Prevent standby if there are active torrents: CHECKED (if unchecked, system will go standby mode before completing the download).




Go to Options>Preferences>Connection


1. Under ‘Port used for incomming connections‘ enter any port number. It is best to use a port number above 10000. I use 54322.


2. Randomize port each time µtorrent starts: UNCHECKED. I leave this unchecked because I have a router. If you do not have a router or a firewall, and want extra security,check this option.


3. Enable UPnP port mapping (Windows Xp or later only): UNCHECKED. I leave this unchecked because I have experienced it slowing down speeds. It is not needed if you manually port forward.


4. Enable NAT_PMP port mapping:CHECKED


5. Add µtorrent to Windows Firewall exceptions (Windows XP SP2 or later only): UNCHECKED (do this only if you have windows firewall disabled)


Under Global Bandwidth Limiting/ Upload,


6. Maximum Upload rate : 9 (for 256 connection)


Note: If you use your Maximum upload speed there’s not enough space left for the files you are downloading. So you have to cap your upload speed.
You can calculate the optimal upload speed…by actual upload speed * 80%


7. Alternate upload rate when not downloading : UNCHECKED







Go to Options>Preferences>BitTorrent




1. Global Maximum Number of Connections: 90 (for 256k connection)This number should not be set too low or the number of connections made to your torrents will be limited. Setting it too high may cause too much bandwidth to be used and can cause slowdowns.


2. Maximum Number of connected peers per torrent: 60 (for 256k connection)If you see that the peers connected to a specific torrent are exactly this number, or very close, increase this number to improve speeds.


Optimize this setting by, calculating upload speed * 1.3


3. Number of upload slots per torrent: 3 (for 256k connection)This depends on how much you want to upload to other users. Do not set too low or it may affect download speeds.


4. Use additional upload slots if upload speed <90%: CHECKED


5. Enable DHT Network: CHECKED. This is recommended to be checked to improve speeds. More people will be available for sharing if this is checked.


6. Enable DHT for new torrents: CHECKED


7. Enable Local Peer discovery: CHACKED


8. Enable Peer Exchange: CHECKED


9. Ask Tracker for scrape information: CHECKED




Go to Options>Preferences>Queueing


Under Queue settings,


1. Maximum number of active torrents(upload or download) : 1 (for 256k connection)


2. Maximum number of active downloads : 1 (for 256k connection)



Go to Options>Preferences>Advanced


Set the value of net.max_halfopen: 50




Maximum download speed
Setting your maximum download speed to unlimited will hurt your connection. So use this to calculate your optimal setting.
download speed * 90%
