If you have maybe 100 chickens in a pool, all the sounds of them clucking and splashing slow the client down immensely. The game also has no ability to turn sounds off in order to increase the FPS (turning the volume down all the way doesn't turn sounds off, it just makes them silent). I would suggest sounds be optimized and the game does something to determine priority of sounds and have an arbitrary limit of like 50 sounds playing at a time or something in order to increase performance.
