Also set uTorrents Upload and Download caps to unlimited.
At uTorrent Preferences Disable UPnP port mapping.
Global maximum number of connections: 600 (If the number you have surpasses this then don't bother, same for below)
Maximum number of connected peers per torrent: 400
Number of upload slots per torrent: 170
At the Queueing tab set Minimum ratio to 1000 (If you're doing fine with a higher number then don't bother)
Try tweaking these settings then see if your speed improves.

i dont think this would help the torrent, what that does is only set the "minimum ratio" to upload of what size you've downloaded, example 1gb downloaded file with a ratio of 1000%, that would mean you're forced to upload 10times it's size.
setting it to zero doesn't give me difference from setting it to 200.

Strange i heard it starts throttling the speed the moment it reaches it's requirement, does setting it to 0 disable it?
I heard setting it to -1 was supposed to make it unlimited but that didn't seem to work.

Doing that is not recommended. When your up bandwidth is saturated, your entire connection becomes a great deal slower. In particular, your download slow to a crawl. And, of course, when you're torrenting enough stuff, your up bandwidth is pretty much constantly maxed.
Ideally, as a rule of thumb, up should always be capped to 80% of your actual bandwidth limit. If you let uTorrent figure out your network's speed when you first start it up after a fresh install, it will do that automatically as well.

It probably does, from what kita said. Setting numeric settings to zero typically disables restrictive settings.
Edit: I just realized that last sentence is a bit of a mouthful. I mean, if a setting is numeric, entering zero should disable it if it is restrictive.

Don't ya need UPnP port mapping if randomizing port each start? I use it as a another means to get around my ISP shaping it's bandwidth. If not randomizing ports, yea, best to open ports manually.
Something else people might want to try is disabling Windows Firewall, if haven't already. That is if already using the router's firewall. DMZ is dangerous.
I don't have a 100mbit connection. Just the average 20/2. No problems when having enough peers for both up and down. Getting max on private trackers. But modifying the disk cache settings benefits everyone when using a large number of torrents. I have one hard drive dedicated to downloads and torrents. Whenever I copy from it, it's noticeably slow. After modifying the disk cache, like posted in this thread, my disk copy/move speed went from around 20 MB/s to 90 MB/s; same speed as with my other drives. Always suspected the torrent usage was the cause. Thanks.

Another way to look at it: You would rather the throttling be done at your computer, than having your ISP do it. The ISP tends to choke everything. Also downloading requires a small amount of upload for communication, which it could be waiting if upload is choked.
But you can use unlimited if using QoS. Optimal for when having multiple apps using the bandwidth.

ok, so i'm gonna compile the useful stuffs i've read about µTorrent settings from uTorrent.com, well most of you guys would've known these by now anyway.
(click to show/hide)
--- Quote ---What ports should I use for µTorrent?
It is generally recommended to not use any port in the range 6881-6889 or ports under 1025. Any other port except for 25 or 110 is acceptable.

--- Quote ---Enabling Protocol Encryption
Some ISPs (Internet Service Providers) actively interfere with P2P activities in order to reduce their bandwidth requirements. This causes µTorrent and other file sharing download speeds to become slow. To avoid this, µTorrent and other clients have introduced an encryption protocol to prevent ISPs from identifying BitTorrent traffic.
Go to Options > Preferences > BitTorrent. Set Outgoing under Protocol Encryption to Enable, check "Allow incoming legacy connections".
Some ISPs have extremely aggressive throttling methods and for those users it might be necessary to set outgoing to Forced; however this will greatly reduce the number of peers you can connect to. Enabled is sufficient for most users

In µTorrent (be it upload or download)
COMMON PROCEDURES (THIS IS A LINK -- CLICK IT)
Restart µTorrent, your computer, modem, and/or router after performing any of the suggestions below
Make sure you have a green network status light in the µTorrent status bar and/or the port checker in the Speed Guide (Ctrl+G) shows the port to be open
Try testing a torrent from OpenOffice.org, Slackware Linux, or Ubuntu Linux? (If any of them run quickly, then the problems you're experiencing likely lie only with the swarm)
Try enabling Protocol Encryption? (Can be found in Preferences > BitTorrent)
Try disabling bt.tcp_rate_control? (Can be found in Preferences > Advanced)
Try various uTP settings? (Set Preferences > Advanced > bt.transp_dispositi on to 31 to enable, 26 to force, 21 to disable)
Make sure peer.lazy_bitfield is enabled? (Can be found in Preferences > Advanced)

--- Quote ---"The Minimum ratio field allows you to set the ratio that you wish to reach before µTorrent throttles the speed for the torrent job (or stops it, if you set it to do so). Setting the ratio to -1 is equivalent to setting it to unlimited. Setting this value to 0 tells µTorrent to ignore this value and look only at the seeding time limit. This value is interpreted as a percentage. µTorrent will throttle the seeding process only after both this and time limit have been reached."

--- Quote ---B. For improving low speed issues:
[1] Make sure your upload speed limit is correctly set as follows:
1a. Set "Banwidth->Apply rate limit to transport overhead" to enabled (very recommended) -
set the upload limit to about 80-95% of your connection's maximum upload-speed/cap.
This is required so to accommodate for 1) + 2) above, limiting the total of
upload-payload + download-acks-overhead
You can test your connection speed @ http://speedtest.net or use the options->setup-guide (control-G)
1b. If you have "Bandwidth->Apply rate limit to transport overhead" - disabled -
set the upload limit to 70-80% of your connection's maximum upload-speed/cap.
This is recommended in this case, but not required, though.
You can set it to as low as the actual seeding-payload speed you like to have.
In both cases you can use a different upload speed limit setting at pref->bandwidth->"Alternate upload rate when not downloading"
Test your download speed again now with this (test torrent...) This step should be enough for most users that upgrade!
[2] Settings that might improve (reduce) your overhead:
2a. Set pref->advanced->net.uTP_dynamic_pac ket_size =false
2b. Set pref->advanced->net.utp_initial_pac ket_size = 8 (use MTU size)
[3] Set pref.->advanced->bt.tcp_rate_control = false
[4] If you want to try and reduce your ISP's throttling:
Some ISPs are more "sensitive" to UPD (uTP) traffic. You can reduce the use of uTP by -
4a. Support only uTP incoming connections by setting pref->advanced->bt.transp_dispositi on = 29
4b. Alternatively - disable the use of uTP by pref->BitTorrent->Enable Bandwidth Management = unchecked

@meomix, have you tried using utorrent 3.0? BBTwhitelist says its allowed now.
