The invention discloses a method and device for improving the running speed of games and relates to the technical field of browsers. The method includes the steps that when a browser of an IE kernel triggers a game page loading incident, a game environment optimizing toolbar is loaded through a browser auxiliary object; optimizing processing of system resources is started according to triggering of the game environment optimizing toolbar by a user. According to the method and device for improving the running speed of the games, in the browser of the IE kernel, when the game page loading incident is triggered by the browser, the game environment optimizing toolbar is loaded through the browser auxiliary object, and optimizing process of the system resources is started according to the triggering of the game environment optimizing toolbar by the user. Thus, the problem that when the page games run in the IE browser, resources occupied by other processes in a system environment are many, and the running smoothness of the games is affected is solved, and the advantage that unnecessary system resources in the game running environment are released, and therefore the effect that the games run more smoothly is achieved.
