Utorrent Global Maximum Number Of Connections
This video is about how to make uTorrent 2.0 faster. The first step that you will have to do is to open your uTorrent 2.0. Once you have opened uTorrent 2.0, go to "options" then click "Preferences". Once you have clicked "Preferences", go to "Connection" found on the left side of the window. Then beside the random port, change the numbers to "45682". After you have changed it, go to "Bandwidth". Then change the maximum upload rate to "15". Also change the maximum download rate to "1890". You also have to change the global maximum number of connections into "200" and as well as the maximum number of connected peers per torrent into "2329". Change the number of upload slots per torrent to "14" as well. Once you have changed everything right, go to "BitTorrent" and check all basic features except "Limit local peer bandwidth". After clicking "BitTorrent", go to "Queuing". Change the maximum number of active torrents to "60" and the maximum number of active downloads into "63". Then the ratio must be 100%. Now go to "Apply" and press "OK" found on the bottom of the window. Test this by downloading some torrents in torrent websites. And if it works, then you're done!
utorrent global maximum number of connections
To configure Azureus for optimum performance, you need to know the upstream capacity of your Internet connection, which can be obtained from your Internet Service Provider (ISP). Advertisements may include numbers like "1024/256 Kbps"; this represents the maximum bandwidth available to you. It is the number of kilobits per second (kbit/s or Kbps) you can download/upload with your connection. You may have seen speed measured in kiloBytes per second as commonly reported by browsers. There is a difference between the two measures. In all likelihood, you upload slower than you download.
It is a Ubuntu Linux distribution, which has lots of seeders, and you should reach your internet connection's maximum speed in most cases (especially with ADSL/cable home connections). Speeds well over 10 Mbit/s (= 1 MB/s as Vuze sees it) should be reachable. You don't have to download the 600 MB torrent completely, but you can use it as a test case for measuring maximum speeds of genuine torrents.
Optimal will also depend on what you're downloading. If you have something popular with huge numbers of available seeds you can make use of that, but if you have something with fewer seeds available it will be preferable to make the most of the few connections available.
Thanks for the info, much appreciated. I have set my download speed to 45000Kb/s and my upload speed to 10000Kb/s. What setting do you suggest for the maximum number of connected peers per torrent? Mine is currently set to 125.
These numbers do not make sense.Firstly, it will be an individual thing, what works for one person may be quite different for a different router.The Global maximum number of connections is the combined total of all connections.You can't have more peers connected to one torrent than the total global total.The number of peers per torrent x the number of active torrents can not be more than the global maximum number of connections.
What setting do you suggest for the maximum number of connected peers per torrent? Mine is currently set to 125.I would suggest the lowest number that allows you to reach your selected speed limits.
You've selected a download 4.5 x the upload. So if you're seeding to just one client, you could be getting 4.5 downloads at your upload rate to reach the limits. I would argue that supports a maximum of 6 connections. Any more connections would only be supported by limiting the speed of each connection.You will have less overhead with a small number of fast connections than a large number of slow connections.
Empirical testing is the only way to find your definitive answer. I'd suggest starting with a small number, say 10. With a popular torrent, see what speed you get. If your download & upload actual rates are less than your set speed limits, increase the number of connections by the proportion of the achieved speed. If for example you reach 20000kb/s download and 5000kb/s upload (ie about half your selected limit) double the number of connections.
I'm currently running 400 global maximum connections, 80 peers per torrent.In practice I'm often tweaking these numbers, depending on what uTorrent is doing and what else is going on.If I want to watch Netflix for example, I might not stop uTorrent entirely but set it's download limit to half my available bandwidth.I tend to tweak the upload limit to keep the grand total in the same magnitude as the download, I'll try and seed roughly 1GB for every 1GB I download.
Yeah, I'd have to agree.I put in my upload speed of 22600 kb/s and it suggests a reasonable speed factor, but "Maximum number of connections" is way over the top, suggesting 1200.Maximum number of connections isn't really a speed issue as much as the capability of your router.
Navigate to properties> Bandwidth, then set Global maximum number of connections to 150 and the maximum number of connected peer per torrent to 100. Leave the upload slot as it is.
There are several criteria a good choking algorithm should meet. It should cap the number of simultaneous uploads for good TCP performance. It should avoid choking and unchoking quickly, known as 'fibrillation'. It should reciprocate to peers who let it download. Finally, it should try out unused connections once in a while to find out if they might be better than the currently used ones, known as optimistic unchoking.
Everyone got all excited when it was noticed that Microsoft had initially limited half-open connections in XP and Vista to small numbers. As a plethora of hacks came out to remove this limit, somehow "half-open connections" became the scape-goat for slow download speeds. Suddenly it became de riguer to advise Windows users to hack the TCP/IP driver and set their half-open connections to something huge, like 200.
You should limit your number of connections because it take resources to keep track of each connection, and why track connections that are giving you a trickle if any data? One peer feeding you 5 KiB/s is worth 50 peers flickering at 0.1 KiB/s. Similarly, you don't want/need to be keeping track of a large number of peers waiting around hoping one of your upload slots comes free.
You can, by setting the per-torrent maximums to less than the global maximums, prevent a single torrent from using up all the allocated bandwidth and forcing all of the other (auto-managed) torrents to pause. But there is no advantage to increasing your number of active torrents. Indeed, by letting the torrent with the best speeds dominate, it will finish as quickly as possible and then stop competing for resources with the other torrents in the queue.
On the bandwidth area by default, the values for Maximum download rate is set to unlimited (showing 0 value), if you see any other value change it to 0 value. Below there is a Global maximum number of connections change this value to 500. Leave other option as it is.
I find that in my P2P application with is uTorrent, limiting connections to a smal number, download to 70% and upload to 50% keeps the very fast PC from flooding the very tiny router. I have OpenWRT and it has the basic 5,000 table-size and I never see my P2P app using more than 300-400 entries in it. Muzzle your P2P app, particularly on residential ADSL lines they can be like ill-behaved dogs you have to get them under control.
vincentfox,Thanks, I am using uTorrent too and have the total number of connections set at 750 which should be manageable by the router my download and upload speed is set low too, but what I think is happening is that the disconnecting takes too long and uTorrent practically uses all available connections.So any other solutions? Do you know how to set the tcp timeout?Thank you.robert
To do so, launch uTorrent and go to Options on top of the page. Then select Preferences and set the maximum number of active downloads to one. Apply and save before closing Preferences.
Here, you can set the maximum upload rate. We recommend that you set it to something in the vicinity of 15. Similarly, increase the maximum download rate to as much as you want. Set the global number of connections to 2329 while also setting the maximum number of connected peers per torrent to 257.
This guide gets you up to maximum speed with BitTorrent using uTorrent and is great for beginners. It details all the steps from downloading to optimizing your utorrent and Windows settings. Many people have used and think they are running with optimized settings, even then, it is advised to read through this guide and see what you may have missed to get the best configuration settings.
The ephermal port range defines the maximum number of outbound sockets a host can create from a particular I.P. address. The fin_timeout defines the minimum time these sockets will stay in TIME_WAIT state (unusable after being used once).Usual system defaults are:
On the Server Side:The net.core.somaxconn value has an important role. It limits the maximum number of requests queued to a listen socket. If you are sure of your server application's capability, bump it up from default 128 to something like 128 to 1024. Now you can take advantage of this increase by modifying the listen backlog variable in your application's listen call, to an equal or higher integer.
