Is there a way to prevent a spawn delay (no script provided)?

This question doesn't provide any code, I tried searching for the answer and I got nothing. My game has a weird spawn delay as the server gets older and I can't figure out why it's doing that. No spawn stuff has been affected, CharacterAutoLoad is enabled, I don't know what is causing spawn delays.

Let's see if this script works, put this code in a regular script in StarterPlayerScripts or StarterCharacterScripts or Workspace.

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:connect(function(chr)
		repeat wait() until chr.Humanoid
		chr.Humanoid.Died:connect(function()
			plr:LoadCharacter()
		end)
	end)
end)
