Im using coroutine allot of times in my game and im scared its gonna cause lag issues to the players of the game.
And if it does cause lag, what alternative to it doesnt cause lag?
Most of the overhead comes from what they’re doing. Using them en-masse shouldn’t be any visibly less performant than, say, using multiple scripts or anything of that nature. Generally, multithreading using coroutines and multiple scripts should be comparable in performance since for the most part they’re the same thing.

If it does cause lag try to reduce the number of threads you’re creating.
How can i reduce the number of threads i am using
Use new threads only if it is really needed, when your script is yelding because of a wait time or a loop.
Share the script and we may be able to point you in the right direction.
i just need to know if there is an alternative for it that is faster and causes ess preformance issues
The alternative would be to create new threads only when absolutely necessary.

you can just re-use the same coroutine.
this is the code for a fake spawn function that just re-uses a coroutine over and over again
local freeThread: thread?
local function passFunction(func: (...any) -> (...any), ...: any)
local thread = freeThread :: thread
freeThread = nil
func(...)
freeThread = thread
end
local function newFreeThread()
freeThread = coroutine.running()
while true do
passFunction(coroutine.yield())
end
end
local function spawn(func: (...any) -> (...any), ...: any)
if not freeThread then coroutine.wrap(newFreeThread)() end
coroutine.resume(freeThread, func, ...)
end
this devforum post explains how it works ig, it’s a tiny bit different from this code, but it does the exact same thing

apparently, stravant’s GoodSignal is where the poster for the tutorial learned the function from
