Description: TCP Optimizer is a free program that provides 1-click acceleration of your internet connection through optimizing your internet registry settings.

The first question on many people’s minds whenever they hear of a program that purports to do something like this is invariably whether or not it is for real. The short answer to this question is yes; for the long answer, you can see the results below of my tests that I conducted with various TCP Optimizer settings.

There are 2 ways to use this program: if you are well versed with the different registry settings you can certainly perform your own custom tweaks across dozens of settings (go here for an explanation of all of these). For most of us, however, TCP Optimizer will automatically find out optimal settings based on one (or two) user inputs, as follows:

  • Connection speed slider: adjust this depending on what the maximum speed of your internet connection as advertised by your internet provider.
  • Network adapter selection: if you are using wireless make sure to set this to your wireless adapter; otherwise leave it alone.
  • That’s it. Click on the ’optimal settings’ radio button and then apply.

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+ :)

If you need help with the program, check the TCP Optimizer documentation, read our broadband tweaking articles, the Optimizer FAQ, and/or visit our Forums. The program can be freely (re)distributed, as long as you give us proper credit as the author, and it is not sold for profit.

"Good program"

by combatshotgun on April 26, 2006

Pros: I'm a beginner here, so I didn't really know how to use this program at first. But the website has a user guide on it.

Or, if you can't be bothered to read it, it can automatically configure the settings for you (but you have to give them your maximum bandwidth speed - CNET has a bandwidth checker).

Webpages load noticably faster now.

Cons: Not beginner-friendly.

"it really does work.."
