Alright so it is faster localizing the functions, so should I do it?
I know its such a small amount

Also the question is about Lua, Roblox Lua and normal Lua are very different, and Lua 5 years ago vs now is very different as well.
Roblox Lua has same functions but are actively modified, maintained and optimized, and with the introduction of Luau, it is safe to say Roblox no longer even uses Lua anymore, it uses a heavily modified version âLuauâ.

Mate, the difference between those times is literally just 2 milliseconds which doesnât even span to 2 frames in 60hz and so the optimization is so slim that itâs not faster at all times. In order to have a noticeable difference you would need to do that iteration 1 billion times which is ridiculous and you rarely need to do 1 billion iterations normally.
It is slower, read the post again and the order of the output and the print statements.

Lol the âfaster methodâ is actually 0.002 seconds slower
What do you mean you literally said the one that localizes math.sine is faster
local tt = os.clock()
-- Faster
local sin = math.sin
for i = 1, 1000000 do
local x = sin(i)
end
print(os.clock()-tt)
Oops, forgot to remove that comment. I copied directly from your code, look at the output results, not the comments.
Any time you âsaveâ (negligible) by localizing you will lose by doing object oriented design 10 times over. OOP is not a fast paradigm in languages like Lua and while itâs not noticeable it probably wastes orders of magnitude more time in calling methods than you will get back from localizing every single operation in a script.
Just stick to normal, readable code. If you want to optimize, look into algorithms and their time/space complexity when you write them.

I think _ENV is something in lua 5.2 and they removed setfenv.
Luau (or roblox lua) uses a modified version of lua 5.1, which doesnât have the _ENV table.
