Poor download speed ismainly a problem with new and very popular torrents where the SLR islow.(Proselytising sidenote: make sure you remember that you did not enjoy the low speed. Seed so that others will not endure the same.)There are a couple of things that you can try on your end to improve your speed:Do not immediately jump on new torrentsInparticular, do not do it if you have a slow connection. The best speedswill be found around the half-life of a torrent, when the SLR will beat its highest. (The downside is that you will not be able to seed somuch. It's up to you to balance the pros and cons of this.)Limit your upload speedThe upload speed affects the download speed in essentially two ways:* Bittorrent peers tend to favour those other peers that upload tothem. This means that if A and B are leeching the same torrent and A issending data to B at high speed then B will try to reciprocate. So dueto this effect high upload speeds lead to high download speeds.*Due to the way TCP works, when A is downloading something from B it hasto keep telling B that it received the data sent to him. (These arecalled acknowledgements - ACKs -, a sort of "got it!" messages). If Afails to do this then B will stop sending data and wait. If A isuploading at full speed there may be no bandwidth left for the ACKs andthey will be delayed. So due to this effect excessively high uploadspeeds lead to low download speeds.The full effect is acombination of the two. The upload should be kept as high as possiblewhile allowing the ACKs to get through without delay. A good thumb rule is keeping the upload at about 80% of the theoretical upload speed.You will have to fine tune yours to find out what works best for you.(Remember that keeping the upload high has the additional benefit ofhelping with your ratio.)If you are running more than oneinstance of a client it is the overall upload speed that you must takeinto account. Some clients (e.g. Azureus) limit global upload speed,others (e.g. Shad0w's) do it on a per torrent basis. Know your client.The same applies if you are using your connection for anything else(e.g. browsing or ftp), always think of the overall upload speed.Limit the number of simultaneous connectionsSomeoperating systems (like Windows 9x) do not deal well with a largenumber of connections, and may even crash. Also some home routers(particularly when running NAT and/or firewall with stateful inspectionservices) tend to become slow or crash when having to deal with toomany connections. There are no fixed values for this, you may try 60 or100 and experiment with the value. Note that these numbers areadditive, if you have two instances of a client running the numbers addup.Limit the number of simultaneous uploadsIsn'tthis the same as above? No. Connections limit the number of peers yourclient is talking to and/or downloading from. Uploads limit the numberof peers your client is actually uploading to. The ideal number istypically much lower than the number of connections, and highlydependent on your (physical) connection.Just give it some timeAsexplained above peers favour other peers that upload to them. When youstart leeching a new torrent you have nothing to offer to other peersand they will tend to ignore you. This makes the starts slow, inparticular if, by change, the peers you are connected to include few orno seeders. The download speed should increase as soon as you have somepieces to share.Why is my browsing so slow while leeching?Yourdownload speed is always finite. If you are a peer in a fast torrent itwill almost certainly saturate your download bandwidth, and yourbrowsing will suffer. At the moment there is no client that allows youto limit the download speed, only the upload. You will have to use athird-party solution, such as NetLimiter.Browsing was used just as an example, the same would apply to gaming, IMing, etc...Last But Not LeastBuy Good Internet Package Which Gives You Rockingg Speed</blockquote>
