The program that you could use to do this is called Gear.(See link in my sig.)

It can speed up or slow down your speed in games or flash players. However, all versions of it(unless you have a friend with it) all have Trojans attached now.

So it won't hurt to tell people what does it.

(Although I'm sure there are other ways)

Edit-

This program is used a whole lot in Half Life:Counter Strike, although it gets alot of other uses.
