Script Optimization

Help and Feedback Scripting Support
1

I have a script for changing graphics. I noticed that it was over 20M in size and I was able to reduce it to around 6M after some changes.
I would like to know if there is a way to optimize it even further. I have tried everything I know, let me know how you would deal with this.

debug.setmemorycategory("Graphics Settings")

local LocalPlayer = game.Players.LocalPlayer
local SettingsData = LocalPlayer:WaitForChild("SettingsData",math.huge)
local Graphic = SettingsData:WaitForChild("Graphic")

local AllBasePartWorkspace = {}

local function NewBasepart (Obj:BasePart)
	if not Obj.Parent or not Obj:IsA("BasePart") then return end
	if AllBasePartWorkspace[Obj] then return end

	AllBasePartWorkspace[Obj] = {}

	Obj.Destroying:Once(function()
		if AllBasePartWorkspace[Obj].Connections then
			for _,ConnectionTab in pairs(AllBasePartWorkspace[Obj].Connections) do
				for _,v in pairs(ConnectionTab) do
					v:Disconnect()
				end
			end
		end
		table.clear(AllBasePartWorkspace[Obj])
		AllBasePartWorkspace[Obj] = nil
	end)
	if VerifyConfigObj then
		VerifyConfigObj(Obj)
	end
end

for i,v in pairs(workspace:GetDescendants()) do task.spawn(NewBasepart,v) end
workspace.DescendantAdded:Connect(NewBasepart)

You can disable Shadows by turning off GlobalShadows in Lighting Service.

3

I also wouldn’t really recommend keeping track of every part in workspace, it use close to no memory if you just looped through each descendant of workspace or if you used CollectionService

4

I am pretty sure tags don’t clean up/GC’d automatically when instance is destroyed, don’t they?

5

Never nesters (me) is dying from amount of nesting

6

I think when an instance is gc’d after being destroyed it frees up all of its memory

7

I do this to avoid freezing and possible crash on lighter devices

8

I think tags are exception to this? Or has this been fixed?

Yes but at the same time you’re also keeping track of every part in workspace, going through each descendant of the workspace with some throttle (e.g; RunService.RenderStepped) would be much better in this case. Using collection service would be an even better fit
