TCP Optimizer provides an easy way to optimize Windows' networking parameters. The developers tried to take into account all related RFCs, the Microsoft TCP/IP implementation oddities and verify that only the necessary Registry parameters were changed.

System Requirements: WinAll
Writes settings to: Windows registry. But given the nature of the application, I think it can be accepted as portable.
License: Freeware
How to extract: Download TCPOptimizer.exe to a folder of your choice and launch.

Once upon a time this pgm. was great and very useful, but for the last few windoze OS it didn't seem to help at least when I used it. I don't wanna say anything bad about this pgm. cuz I have no doubt that for many, many OS systems it is a real game changer and will greatly improve system speed and performance.

I notice no performance boast at all with neither my online games or web browsing. (capture code: "has tizzies" - lols)

gamerman. dont worry just save settings with program
Using the program

If you do not feel like reading the entire documentation below, or you simply need the tweaks NOW, without spending time in learning the meaning of all those settings, you can use the Optimizer by following these short instructions:

- Choose your maximum Connection Speed from the slider bar (the maximum available bandwidth, in kilobits per second)
- Choose your Network Interface, or check to Modify All Network Adapters
- Pick "Optimal settings" from the radio-buttons near the bottom of the program
- Click on the "Apply changes" button and reboot

I have a bad connection (high ping) on certain games.. will this remedy it? My speed is at 1.5 Mbps which is pretty average where I live. Others who live in the same area have slightly better ping. So maybe it's the computer settings? Has anyone tested this?
