I recently enabled the new roblox audio API in my game (used to make a walkie talkie system). I have noticed for 3 days that my servers are particularly slow. So I carried out several tests with around a hundred players to check where the problem was coming from.
It turns out that Roblox’s new Audio API, when activated, generates an “[Unknown]” script whose frame rate increases exponentially (serverside). With each connection/disconnection of a player, it increases, to the point where it can wait for several million executions per second. I had to temporarily disable this new audio API.
