SG TCP Optimizer
TCP Optimizer 4 (latest stable release that works with Windows XP, 7, 8, 8.1, 10, 2012 Server, etc.)
The TCP Optimizer is a free, easy Windows program that provides an intuitive interface for tuning and optimizing
your Internet connection. There is no installation required, just download and run as administrator.
The program can aid both the novice and the advanced user in tweaking related TCP/IP parameters in Windows,
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+ :) It is completely
free, requires no installation, and has been downloaded over 8 Million
