SpeedGuide TCP Optimizer v4.0.0 Beta

Freeware
Vista / Win10 / Win7 / Win8 / WinXP
SpeedGuide TCP Optimizer is a useful free tool you can use to optimize your Internet connection in Windows.

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 tool was developed and is distributed free by SpeedGuide.net
