Remove limit of Half Open Connections to get maximum Download speed in Emule and Torrent

There are several tricks to improve download speed in eMule ,uTorrent and other P2P clients. But perhaps the key element common to both systems sharing/P2P file is related to the limit imposed by Windows for the so-called "Half Open Connections". In fact, starting from Windows XP SP2, Microsoft introduced a limitation to a maximum of 10 half open connections, for security reasons: the half open connections (or connections that remain in state SYN) normally when you have such as a virus (such as the notorious "Blaster") tries to open at the same time a large number of connections to different IP address.

But as you well know, in addition to viruses and malware, including all the P2P software work with the same principle and need to open a large number of connections to different ip address! For this reason, anyone who wants to push up eMule Torrent or she is to apply a patch that removes this bottleneck. The solution that normally I have always used the patcher LvlLord's Event ID 4226 which in fact does physically changing the system file "tcpip.sys" to increase the number most of the half open connections.

But this solution also creates a path for Viruses and Malwares to open multiple connections.Hence i don't recommended this method. Another solution to this problem is TCP-Z.



TCP-Z is a much more evolved than the patcher LvlLord's Event ID 4226, as it achieves the same result, however, applying the changes directly in memory, without any physical alteration of system files in Windows. Obviously the patch applied in memory remains active until you restart, so you must reapply every time you turn on your computer. But this is just one of the characteristics of TCP-Z: it has a monitoring console that displays the status and number of all open connections halp open, displaying the speed of download and upload in real time and any warning due to overloading.
TCP-Z also works in two different ways:

1. manual mode: it consists in 'start the executable TCPZ.exe and then customize the limits of half-open connections in positioning tab "Patch"
2. mode virtual device consists installing TCP-Z as a virtual device. To activate this mode, you need to installaizone device launching the executable TCPZ_Setup-x86.exe, then you can manage connections halp-open directly from "Device Manager> TCPZ Driver> TCP Half Open Limited Patcher (TCP-Z) "

TCP-Z is free, portable and runs on all versions of Windows 32 and 64 bit. Note that, like LvlLord's Event ID 4226 TCP-Z also could be traded like a virus from your antivirus: If you happen simply ignore the messages dell'antivirus.
