Void Update, OnPlayerInput etc. Performance?

I notice a lot of plugins use these. Even though they execute code only if certain state is true (if (test != null)), will they still affect performance to the point where you can see loss of server frames?

Let's say you have 3 plugins using OnPlayerInput with 300 server fps and 100 players online. The code (if (test != null)) is run even if player stand still and no buttons pressed, correct? So 3*300*100 = 90 000 checks per second, seems a lot but maybe it doesn't matter?

I'm just getting into C# oxide so I'm very curious about what to look out for that may affect performance in bad ways. Any tips and advice greatly appreciated.

 

I can give an advice, use Unsubscribe() to unsubscribe a hook that not needed anymore.
Also, try to replace intensive hooks with your own solutions, like you said Update() from MonoBehaviour.
