Re: Optimizing the Network and Internet On Windows 7

Reducing latency for games:

When you play in a network (local or Internet), the latency is very important. It corresponds to the response time between when you press a button or move the mouse and when the desired action is executed in the game by default, Windows combines small packets into one before sending (algorithm Nagle). By disabling this feature, small packets will be transferred immediately, without delay, thus reducing your latency.

Caution, this can slow down your file transfers. To implement so when you want to play network games and just after your downloads. Note that this operation is valid for Windows Vista (with SP1) and Windows 7.
  • Click the Start button. In the Search field, type the command regedit.

  • Click the right mouse button on the program regedit.exe and select Run as administrator.
