If you have a little knowledge in Networking you can modify the TCP/IP settings and increase your Internet connection speed. But don’t worry if you have got no idea about networking. There are many free tools to do the job for you. TCP Optimizer is one such freeware which can be used to tune and optimize your Internet connection. The SG TCP Optimizer works best for optimizing your broadband Internet connection, but I guess you can also use it for other connections also.
TCP Optimizer works by tuning up all the important TCP/IP parameters. It does a lot more than just optimizing your browser. TCPOptimizer basically modifies your MaxMTU and sets it to the value that best suits your Internet Connection. This will definitely help you to get good connection speeds. TCP Optimizer will be useful for both the novice and advanced users in tweaking TCP/IP parameters in the Windows Registry, making it easy to tune your system to the type of Internet connection used. It uses complex algorithms and bandwidth delay product to find the best TCP Window that is more appropriate for your specific connection speed. It provides for easy tuning of all the TCP/IP related parameters like MTU, RWIN etc. You can also modify the advanced parameters like QoS and ToS/Diffserv prioritization. It also includes additional tools like testing average latency over multiple hosts and finding the largest possible packet size (MTU).
