Edit: This issue has been resolved. Thank you Roblox team!
When I have a script clone about ~20 long? sounds into a few parts, the client and server freeze or slow down severely.
Steps to reproduce: Clone a large list of sound files multiple times from ReplicatedStorage/ServerStorage into parts in the Workspace. The longer the sound is seems to affect the client more severely.
Above is an editable demonstration place. If a video or computer specifications is required, I will provide them.
