Can remote event stress the server if we fire it too many times?
Can it affect the ping as well?
I’m sure if you do anything too many times it can stress the server, what example did you have in mind where you’d need to rapidly fire a remote event?
You can test it yourself and see! Firing it too frequently will error and tell you in console you’ve exhausted the remote event.
If it wasn’t a question of how rapidly you can fire it, but instead the processing time impact it’d have, that would be up to what’s executed when that event is connected on server/client.
