Increase internet speed using Tcp optimizer and Half-Open

You can increase your internet speed using tcp optimizer



The program can aid both the novice and the advanced user in tweaking related TCP/IP parameters in the Windows Registry, making it easy to tune your system to the type of Internet connection used. The tool uses advanced algorithms, and the bandwidth*delay product to find the best TCP Window for your specific connection speed. It provides for easy tuning of all related TCP/IP parameters, such as MTU, RWIN, and even advanced ones like QoS and ToS / Diffserv prioritization. The program works with all current versions of Windows, and includes additional tools, such as testing average latency over multiple hosts, and finding the largest possible packet size (MTU).

Open tcp optimizer in the tcp optimizer window select optimal settings radio button Click on apply changes and click on OK and Click on No when it asks for reboot

After tweaking MTU you can use half-open to change the tcp ip connection limit Half-open limit fix is a program designed to change the maximum number of concurrent half-open outbound TCP connections (connection attempts) in the Windows system file tcpip.sys. Microsoft first introduced this limit in Windows XP SP2 (Service Pack 2) and is present in all later versions of Windows. This was done to try to slow the spreading of viruses and malware from system to system and also to reduce the impact of infected systems participating in DoS (Denial of Service) attacks. This limit makes it impossible for Windows systems to have more than 10 concurrent half-open outbound connections. After 10, new connection attempts are put in a queue and forced to wait. Therefore, the speed of connection to other computers is actually limited. P2P (peer-to-peer) programs (µTorrent, BitComet, eMule, P2P TV etc.) are generally the most affected programs. As they use up all 10 of the half-open connections, other Internet activity, especially the loading of web pages, can be extremely slow. The delay before the beginning of opening can make some tens seconds. This happens regardless of the speed of your Internet connection. Half-open limit fix takes care of this problem by increasing the maximum limit of half-open connections. For the overwhelming majority of Internet users, changing the limit to 100 will be more than sufficient.

now open half limit and select the language as English and click on add to tcpip.sys.

This will improve the internet performance on your DSL and cable internet lines. If you want you can restore the settings also by clicking on restore original file because sometimes your ISP router may have a limit on no of tcp ip connections.

If you have firefox you can install tweak network addon to improve the speed in firefox

after installing tweak network restart firefox and open tools menu-> tweak network click on OK now click on power and click on OK.

that was nice information, and this is my suggestion to speed up internet, delete all temp files in your computer, because this might a reason for slow internet, try this after doing my suggestion...if you wanna check your internet speed at any cost test here
