SG TCP Optimizer is a useful program to tweak TCP and IP related parameters in Windows Registry to speed up Internet speed.
No matter what type of Internet connection you have, whether it’s cable modem connection, DSL connection, lease line or dial up connection (28.8/56k), this program will improve your connection performance after the tweaking.
It takes into account all related RFCs, the Microsoft TCP/IP implementation oddities, verifies all Registry locations for the same TCP/IP parameters (ICS Sharing, AOL protocol MTU, etc) and only adds the necessary Registry parameters during tweaking process.
It does support Windows 9x, ME, 2000, XP, XP SP2 and 2003. Most likely you can find it to support Vista soon.

Before you use the program, you need to find out your connection speed. Use the SG Speed Test to find your true connection speed. Please use the closet mirror to your location to do the test; this will ensure that you will get optimum results in the end.
The test should give you 2 figures in it's test results: Download speed and Upload speed, both in Kbps. As a thumb rule, your connection speed is the closet Kbps/Mbps of the download speed.
For eg: In the above screenshot, the download speed is 359 Kbps. So in SG TCP Optimizer we're going to select 256 Kbps as our connection speed.
If your connection speed is in Mbps, then just multiply 1000 to the figure you get from the download speed test results to make it as Kbps. For example, 1 Mbps is 1000 Kbps and 3 Mbps is 3000 Kbps.
Now that we know our connection speed, start SG TCP Optimizer and set the connection speed slider to that matches your connection speed.
Proceed to tick Modify All Network Adapters, and then select Optimal settings to tweak to optimal settings automatically. Finally click Apply changes.
Tick the Backup option to backup existing registry settings and click OK, after that reboot the computer.
Note: Before applying the changes, you can always go to File and select backup current settings, so that you can have options to restore backup settings or Restore Windows Default settings later.
Thats it. You're done.
Note: If you don’t feel satisfied about the result by using Optimal settings, you can always select custom settings to do manual tweaking. Read this TCP Optimizer Help to understand more about TCP/IP settings and other program features you can play with before doing manual tweaking.
