Speed Optimizing Guides for Specific Bittorrent Clients This article was originally designed to help achieve the best download speeds in the four freeware bittorrent clients suggested as Top Picks in my review here at Gizmo's Tech Support Alert. If you have one of the bittorrent softwares listed below, then you should use that guide as it is more detailed and contains screen shots. The picks have changed slightly and there are now eight guides: • • • (also applies to BitTyrant and older Azureus versions) • • • • • • • • If you use another bittorrent program, then this general guide will help. These steps are basic to any bittorrent client. This guide is part of a series of help guide for torrents here at Gizmo's Freeware. For a complete listing of the bittorrent help pages, as well as some other helpful software review links, see • Introduction All bittorrent programs need to have their incoming and outgoing communications flow freely in order to achieve the highest download speeds and that is what this guide is about.

Is your torrent downloading slow? Find here, the most powerful tricks to boost Bittorrent downloading speed by 250%. Know secret settings and tools.

This guide was put together using information given by the developers of bittorrent programs at their forums, guides and FAQs. There are no secret tricks, just the real basics of proper set up of a bittorrent program. Following these simple steps should result in increased download speed. These are the basic principles of optimizing a bittorrent client for speed: • Choose a proper port to avoid ISP blocks and conflicts with other programs • Forward that port through any software firewall and router to allow incoming connections • Adjust internal settings based upon upload capacity of the internet connection to allow room for outgoing communications and to distribute upload efficiently.

There are some programs that claim to optimize speed in bittorrent clients.Such programs are a scam and generally contain adware or spyware. I have seen it said, by the developers of all bittorrent programs, that nothing will increase your download speed in a bittorrent client more than the basic steps set forth herein. Choosing A Proper Port To avoid messing up a network connection that is already cleared, first check and see if your communications are blocked or are already clear. Have your bittorrent client running while testing the port. Success just go to Error - follow all steps. Choose a Proper Port: If you failed the port test above, then you should first set your port to a proper one. The most important choice here is to avoid using a port within the 6881-6999 range.

This was the range originally used by bittorrent programs and is often blocked by Internet Service Providers (ISPs). (If your port was in this range, change and re-test). The safest choice is a port in the 4 range as this will avoid ISP blocks and possible conflicts with other applications. This range used to be 4, but apparently Vista and Windows 7 grabs some of those ports in between. Windows users, if you want to make certain there is no conflict.

And type in netstat -a >c: log.txt This will check to see which ports are being used and save a log text file at C:. Looking at the text file, you will know which ports to avoid.

Forwarding The Port Introduction A router will block incoming communications unless an exception is made. All software firewalls will block incoming communications and most will also block outgoing communications, unless an exception is made. If you are 'firewalled', then other people will not be able to initiate connections with you (see ). As there are many firewalls and routers, this guide can not give explanations as to each.

However, there are guides available, on the internet for most firewalls and routers and this guide will link you to them. Software Firewall - The permission should be set to allow TCP and UDP in both directions.

Generally, you will have a choice to set permission for the port or for the bittorrent program. Setting permission for the port is the safer choice. You can check these options for guides: • The help file of your software firewall is the best place to look • has some guides posted • (choose firewall and then your program) also has some guides. Router - There are two choices here.

The easier way is to use UPnP. However, this has a Using UPnP allows any program to create a port mapping through the router without consent of the owner. Note: Given the, it is generally suggested here that manual forwarding be used. If you still want to use UPnP, then it would be a good idea to The other choice is to manually forward the port through the router.

This does not have that security issue, but involves going through several steps to accomplish. Using the guides linked herein, this should not be that difficult and is the preferred method. UPnP (NAT-PMP in Apple) - The Easy Way - Enable UPnP (NAT-PMP in Apple) in your bittorrent client and router. Manual Forwarding-The Preferred Way • UPnP (NAT-PMP) Must be disabled in bittorrent client and router. • Set permission for the bittorrent client's port. This should be set to allow both TCP and UDP communications.
