Are you talking about FPS lag or internet lag? If it is FPS lag, there are a number of ways to help, such as lowering your graphics settings, closing background tasks, etc. If you are experiencing internet lag, we suggest using an ethernet connection if you are not already. If you are already using a wired connection, there is not much else you can do besides upgrading your internet speed.
