This doesn't have to be just an application also I don't believe you learn how code works/file size, etc as a staff member. Also as a game master you don't need to know any of that, you're able to give game masters an introductory training on how to effectively execute their ideas for events which this can be done on the event server.
I think you were meaning lag to the server if so all you have to do is put that into an introductory training which even before this it's common sense on how to keep lag down.
