Ways to Reduce Multiplayer Online Lag in Video Games

There are several ways to reduce a laggy game experience but the performance gain is minimal, Few of them are :
1. Shutting down all downloads and sharing applications like bittorrent.
2. Placing Wi Fi near the pc or console, make sure it does,nt has to go through a wall.
3. Connecting to internet directly reduces the latency because every time net touches a hardware, latency goes up, More latency potentially more lag.
4. Nothing can slow you down like a good dose of spyware, keep them out of your system by periodically scanning the system.
5. Make sure your hard drive has enough free space between one third or half if you are running game on a low ended system.
6. Make sure all the extraneous programes have been shut down.
7. Do not try to over clock your computer, while this increases its  processing power it dramatically shortens its life span and increases the risk of overheating.
8. Allow your computer a cool-down-period for better performance.
9. Disable unnecessary drivers and windows services, close background application processes.
