As most people know sp3 drops more limits on things This lil tool undoes them.

TCP/IP Changer Here
If your going to use this tweak don't change it to 10,000 as it says on the page. anywhere from 100-500 will be fine.


;;; More Guides also on youtube. (I just put a few of them together)

Just a warning to all of you who are going to try this..it might screw up your torrent..

Er... OP is missing the tiny eety beety fact that adjusting uTorrent settings will be RELEVANT to your system and your connection speed. And obviously, you shouldn't change preferences if you have no idea what they do.

What anyone should be doing is to add uTorrent as a firewall exception. You should already have this enabled anyway, because Windows Firewall will prompt you whether you want to let uTorrent's traffic through or not from the get-go.

It's best if you actually leave Randomize Port unticked and specify a port of your choosing, preferably a port above 10000. When you specify a port, you have the opportunity to open that port and thus let traffic go through as you please through your router (if you have one). And of course, setting up port forwarding is specific to each router, which help on setting this up can be found on PortFoward.com.

UPnP stands for Universal Plug and Play. It makes recognition of devices on your network... well, easier, theoretically. I haven't missed it; therefore I've turned it off personally. I would think that this would improve performance through your router by a very, very slight bit... but adjust this at your own discretion.

NAT-PMP, basically, allows for automatic port forwarding. I would trust manual settings and, therefore, if you are forwarding a port yourself, to turn this off.

Setting an automatic download and upload rate is not recommended because uTorrent is probably not smart enough to know your bandwidth allowance... so I would actually keep this unchecked. What you should do is test your connection at SpeedTest.net, take the numbers IN KILOBYTES (KB) and not KILOBITS (Kb), multiply those numbers by 80% (.8), then put those numbers into your upload and download limits. This way, uTorrent won't rape your bandwidth.

Global connections would be the number of connections to peers that uTorrent will make. Connected per Torrent would be the number of peers that you will make connections to per torrent. Making any of these numbers astronomical will net you no more performance than setting this to a smaller, more realistic number. Depending on your bandwidth allocation through your ISP, I would set this to a more realistic number. See the chart and source that I have in this thread, which actually covers the same topic this thread does.

Protocol Encryption is a good thing as it encrypts your data going in and out, which means that ISPs can't analyze your P2P traffic and consequently "choke" your transfer rates. (ISPs don't like peer-to-peer.) 

The numbers that Ash-Bash puts out are insane. You should never have 60 torrents active, and 63 active downloads when you already specified 60 active? Whoever made the article that Ash-Bash quoted didn't do their math right.  Refer to the aforementioned chart, or you can safely go with something low, like 5 active torrents and 4 active downloads. This will ensure decent speeds with downloading AND uploading, since you won't be struggling to download and upload from a ton of peers. The reason why I say that is because, with the settings Ash-Bash posted, you would be connected to (60 active torrents x 200 possible peers per torrent - 12000 connections, but limited to the 500 global connections you specified earlier). Check your math... it makes more sense when you do, and it ensures that you're not telling uTorrent to do the impossible. 


Everything else, I would leave alone, except for the net.max_halfopen parameter. This allows you to make as many connections as you can, but setting this to a high number does nothing if your TCP/IP settings won't allow it. LvlLord's Event 4226 TCPIP.sys patch lifts the limitations of XP and Vista as far as connections go (implemented by Microsoft as a propogation measure in the case of infection by malware) but there's only so much you can gain by applying this patch and modifying this parameter.

Again, I want to refer to you to my previous post in the other uTorrent thread for more information. There's a lot of false information out there... so common sense rules all.  Remember that these settings are dependent to your bandwidth allowance. There are no magic numbers for uTorrent that will make rocket go boom. 

If there are any tools that may speed up you torrent?

There are like hacked versions of utorrent and stuff that are supposed to help, but, as usual, if nobody's sharing the file, then it's going to be slow or impossible to download anyways. Assuming your firewall is set up correctly as rayzoredge described, your download speed should only be limited by the number of peers/seeds and your connection bandwidth.

it's impossible to speed up utorrent imho.
torrent bandwidth speeds are dependent on the network speed..

lastly, why use utorrent when it was acquired by the same company who hates P2P? don't you think something fishy is up?
Go open source! been using this one for a while now: http://www.binarynotions.com/halite-bittorrent-client

Guys, do you if there are some tools or information that can speed up the uploads?

I just gave you AND linked you to information to speed up downloads AND uploads.


You can only download as fast as a peer is sending you the information, capped by your bandwidth allocation. Basically, if I can upload to you as a peer data @ 400KBps (my upload transfer rate), but your bandwidth only allows a 200KBps download limited by your ISP service, then you can only get 200KBps of data, no matter what you do. The only options here would be to upgrade your service through your ISP. The same concept applies if I had a crappy connection to you as a peer. If I could only send you a maximum of 192KBps because that's my real upload cap thanks to me being cheap and not wanting to pay more for more bandwidth, even if you had a 400KBps download allowance, you would only get my data at anywhere from 0KBps to 192KBps, depending on any other number of factors.

The best thing to do to maximize your upload rate is to upload one to a few torrents at a time and actually have decent bandwidth to do so. However, keep in mind that the more you reach the cap for your upload rate, the less data you will be able to request (which makes Internet browsing very, very painful; see my previous post). If you are looking to improve your download/upload ratio, and if you have a good connection to the Internet, seed only a few torrents that are moderately desired, unless you REALLY have an awesome Internet connection.

Think about this for a second. If you are uploading a torrent that has 100 leeches and only a few seeds, you will almost be guaranteed to connect to a bunch of these leeches and seed your file at [near] YOUR bandwidth cap, because people will be wanting to snag more data to finish their download. However, if you are uploading to a torrent with 99999 seeds, don't you think that out of the 99999 people seeding, a ton of those people probably have decent if not a better Internet connection than yours? If you are "competing" to seed and you "lose," you will be stuck with seeding fragments of files at lower transfer rates to complement the people who's bandwidths can afford to feed leechers large fragments of files at higher transfer rates. Remember that you are seeding FRAGMENTS/PIECES of files and not actual files. That's how the swarms works together to give everyone what they want, cooperatively.

There are people out there who might have a real fast network at their workplace, but for obvious reasons your employer would have firewall setup in such a way that you wont have active incoming. To fix this you can try a simple yet effective technique which I have put to good use recently. You can change the port to use to something which is out of this range 49152–65535
'Cause applications use those ports, and hence those are ports which get blocked first

There are many Tutorials out on the Internet, Andmost of them are Scams. I found some Good ones ive come Across before and Some I havent. So just make sure you read the Comments if there is any. But dont change any settings if your not sure.
