Does shooting a lot of raycasts cause memory leaks and decrease performance?

This is pretty simple, I’m just asking does shooting too much rays result in low performance.

Raycast Performance

Hey, So I wanted to run a local script that is casting rays everytime it loops to create an arcing grenade, my question is if this would cause any performance issues on the client because of the frequent looping of the rays? Thanks.
