I've felt this way for years about tennis. There should be a time limit imposed on serves.
Grunting should be banned as well as it must be off-putting for an opponent.

Golf however imo is different. Some of the great shots in majors have happened after the player has taken an eternity to weigh things up.

I give you Tiger Woods Masters 2005 16th hole
