uTorrent Tweaking
---Open up µTorrent and go into its Preferences. Get a calculator ( Windows has one built-in ) if you can't do basic math, because you're going to be calculating for the most Optimized Values for your connection by hand.
The example we'll use: 3000 kb/s Downstream and 384 kb/s Upstream.
Be sure to replace these values with your own download and upload speeds when doing the math. I have selected 3000 / 384 kb/s because it represents most of the standard Cable Connections and to give us a broader spectrum to work with as an example.
Go to:Options / Preferences / Network Options.
---Assumeing you've forwarded your port, look at the Global Maximum Upload Rate. To calculate this value is very simple. Take your maximum upload speed (in this instance 384 kb/s) and divide it by 10. *Note: if you're a high-bandwidth user (>768kb/s), you may substitute 10 with 8.
GMUR: 384 / 10 = 38.4
Use about 75%~85% of this value. If you have a really slow upload speed, 75% is more forgiving, but if you're on a really fast connection, feel free to use a higher percentage, like 85%. Going higher than 90% is not recommend, because this will be too close to your maximum upload speed and will probably choke your bandwidth at some point.
GMUR: 38.4 x .80 (80%) = 30.72
GMUR: 38.4 x .75 (75%) = 28.80
µTorrent only allows you to use whole rounded numbers, so on this ocassion we'll use 30. If you experience some websites that are timing out, or you're having other types of problems ( like difficulty sending e-mails ), feel free to lower this to 28. However, if you're primarily seeding and are barely using the PC for Web browsing, you can safely use 31. for this example, leave it at 30.
Global maximum upload rate (kB/s) = 30
Alternate Upload Rate when not downloading can be selected by you, depending if this applies to you or not. Whatever you're going to do, don't set it higher than 90% of your maximum upload speed.
Global Maximum Download Rate is calculated similarly. Take your maximum download speed (for this example it's 3000 kb/s) and divide it by 10. Note: if you're a high-bandwidth user (>5000 kb/s), feel free to substitute 10 with 8.
GMDR: 3000 / 10 = 300
This time, we're going to use 80%~90% of this value. If you have a really slow download speed, 80% is a bit more forgiving, but if you're on a really fast connection, feel free to use a higher percentage, like 90%. Going higher than 95% is not recommended, because this will be too close to your maximum download speed and will probably choke your bandwidth at some point.
GMDR: 300 x .85 = 255
µTorrent only allows you to use whole rounded numbers, so in this instance use 255. This leaves plenty of download bandwidth to surf the Internet without slowing down. If you think these values are too low for you, experiment with higher numbers and see which ones work best for you. IMPORTANT, unless you have a QoS (Quality of Service) software installed, never leave your download and upload speeds uncapped, this can only result in bad speed and ruin things for everyone on the swarm. Again, these recommendations are simply a guide to find your optimal settings. You are the one who'll ultimately have to determine the best settings for your configuration.
Global maximum download rate (kB/s) = 255
*Again, unless you have a QoS (Quality of Service) software running, never leave your download and upload speeds uncapped.
*Another benefit that seems to be derived using Bandwidth Caps for Client Max Global Limits, (Upstream and Downstream) is less or no interuptions (drops) from your ISP. This also allows you Modem to maintain a more constant bandwidth stream.

---Global Maximum Number of Connections. This value is very, very easy to guess. Just take your upload bandwidth in kb/s and put it in there. In this example it's 384 kb/s, so put 384 as the number.
Global maximum number of connections = 384
---Maximum Number of Connected Peers per Torrent. The value that seems to work best, is as follows: Take your upload speed (in this example it's 384 kb/s) and divide it by 8.
MNoCPpT: 384 / 8 = 48
Put that number ( 48 ) in the box next to it.
Maximum number of connected peers per torrent = 48
---Number of Upload Slots per Torrent. This number should obviously never fall below 1...keep that in mind. In case you have a really low or slow upload speed, like 56.3 kb/s (standard dial-up), keep it at 1. However, You could try 2. To calculate this value, you'll need to refer to Network Options in this example. Look at the number you put at your Global Maximum Upload Rate (in Network Options). In this example it was set to 30 and you divide it by 4.
NoUSpT: 30 / 4 = 7.5
For this example, we'll use 7 upload slots per torrent. However, tick (check) Use additional upload slots if upload speed <90%. Just in case someone needs those extra few bits.
Number of upload slots per torrent = 7
Use additional upload slots if upload speed < 90%
---Queue Settings: Here you have two settings that nobody will agree on. However, use common sense when setting these. By uploading pathetic little bits here and there, it's only going to hurt the BitTorrent community even more. So be cautious when downloading (don't try running everything at once) and once you're finished don't forget to seed back to others who also want to enjoy what you've downloaded.

Enable Scraping: regularly checks the health of a torrent (how many seeds/peers there are etc.), suggested enabling it.

Unless you're having severe disk space problems, it's better to Pre-Allocate the space to the torrent. It is known, that it also reduces constant writing significantly:
