How expensive is looping though a table

[BaseplateB0T (Baseplate)]

In my game i may have a table that looks like this with maybe 100 values or so

module.data = {
	['Bloxy_Cola'] = {
		DisplayName = 'Bloxy Cola',
		Value = 20,
		Weight = 100,
		RarityColor = rarityColors.Common,
		ViewportPosition = Vector3.new(-61.511, -1.008, -0.324),
		ViewportOrientation = Vector3.new(-3.756, 47.705, 11.278)
	},
	
	['Bloxy_Cola2'] = {
		DisplayName = 'Bloxy Cola2',
		Value = 20,
		Weight = 50,
		RarityColor = rarityColors.Common,
		ViewportPosition = Vector3.new(-61.511, -1.008, -0.324),
		ViewportOrientation = Vector3.new(-3.756, 47.705, 11.278)
	},
}

How expensive is an operation like

for dropID, dropData in module.data do

end

im sure it matters more or less depending on what you actually do with that data but how worried do i have to be about simply reading and maybe saving some of the info into vars?

It’s not super expensive, you can loop through a table a lot of times without suffering any actual performance issue.

But, if you want to be more precautious then try looping in parallel luaU.

@awry_y

if you want to be more precautious then try looping in parallel luaU.

I haven’t truly dabbled in Parallel LuaU yet, but this resource might help!

ActorGroup | Split Heavy Computation Into Parallel Threads

ActorGroup is a utility module I’ve made for the purposes of doing heavy computations (such as frequent spatial queries or generating big arrays) fast by splitting it up into multiple Actors. This module uses queues to manage workers as to not overload a single Actor with tasks when there are free Actors. Documentation:

Constructor

The constructor for ActorGroup is quite straightforward, but it can still be pretty confusing, so here I will explain it. <a class="lightbox" href=&q…

Honestly exiting and entering parallel threads is more expensive than looping The tradeoff isnt worth it in this case

Ah, sorry. As I said, I don’t know much parallel, so thank you for stepping in and correcting me.
