Optimize Dialup, DSL and Cable all from one interface
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.
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 and requires no installation.
You can also pick from Windows Default, Current, Optimal or Custom options for the general setting of the program depending on your chosen Connection Speed. In case you decide to go Custom, a very generous number of options will become available for selection. You are able to work with the TCP Window Auto-Tuning, TCP Chimney Offload or ECN Capability features. Just make sure you are accurately documented as any faulty setting may result in deficient speed and weak security.
Once you open up the Advanced Settings tab, a new wave of options unveils itself. They're split in categories for Internet Explorer Optimization, Host Resolution Priority, Network Memory Allocation, Type / Quality of Service, Gaming Tweaks, DNS Error Caching or Dynamic Port Allocation. The BDP (Bandwidth Delay Product) tab section offers a calculator for quick approximation of RWIN (TCP Window) values.
You are also given the tools for MTU / Latency tests such as Largest MTU or Trace. If all of these have only open your appetite for connection tweaking, the last tab of the application comes to sum them all up. This is the registry zone and you are in full control of the TCP/IP, Internet Settings, DNS Cache, LanManServer and LanManWorkstation keys.
TCP Optimizer can be easily regarded as the top tool for this specific job of Internet connection tweaking. Its feature list is massive and the fact that it actually does what it's supposed to boosts it in the front of the pack. Powerful yet easy-to-use software is always welcomed and TCP Optimizer is one serious addition to this thin crowd.
