Would having many characters inside large CanCollide off parts cause lag? If so what would be a better option

Im currently using the zone module to have region detection in my game, I’m not sure how this would run if I had many players inside a part, is there anyone who has experience with this? If it would cause lag what would be a better option?

Have you tried it?
It may also depend on how often you are checking for Players within the zone. If you’re doing it 60 times a second that might be a bit much, but if you can get away with doing it twice a second that would help.

I havent tried it yet as to just ask for anyone that has so I dont waste time, and because roblox studio test can only go up to 8 players; and im not sure how often it checks but ill check that
