Why do so many things run in the backround ?

Title . Also will they continue to do so after the Open Beta release ? I mean 3(!) LeagueClientUX are running when i play a game . In the old client i play a game with 144 fps and in the new with 40(!) maximum. Is this a known problem or it will be the standard ? Please tell me !
