how to increase the performance of my mohaa players?(its slow as a rock)

[lazers]

When i'm on multiplayer mod my player is just slow. Sometimes i have clicked the mouse fire button but it doesn't fire and my players just walks slowly. I see other players running all over the map mine doesn't. This is why i'm getting some serious beating by some senior players.

My spec are:
pentium 4 2.80 ghz 1.2 gb ram
