The top two are speed boost; set to None and OFF.
Here are my selections for what I have turned ON, for what it's worth - some info is valuable for play; a lot of them are resource wasters or a PITA. Remember if u have ur browser set to clear cookies on closing, you'll have to do this every time u fire up to play.
