TCP Optimizer 4.1.1 full description

Optimizing your Internet connection takes time and requires a certain set of skills in order to be properly done. While it's not a must, you are sure to get a boost in performance and security, as your connection, by default, does not operate at its best. This happens due to operating system restrictions. This is the time for specialized software to step in and bring the set of needed tools for this particular operation.

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).

The TCP Optimizer is targeted towards broadband internet connections, however it can be helpful with tuning any internet connection type, from dialup to Gigabit+ :)

TCP Optimizer 4.1.1 Windows 7 release notes

New Release
Changed the recommended "optimal" congestion control algorithm from CTCP to CUBIC for newer Windows 10 and Server 2019 builds. CUBIC works slightly better for pure throughput, CTCP may work slightly better for VoIP and gaming in combination with ECN and lossy connections.
