Not quite — instead, when the plugin registers with a hook, it stores
the function callback with the hook. So when the hook is triggered, it
simply iterates through each callback.

It doesn't have to ask each plugin whether it's registered with that
hook or not every time the hook is called. That sort of behaviour is
reserved strictly for use within Microsoft operating systems. :)

But yes, there are performance penalties associated with the use of
plugins. That's the price you pay for convenience. But plugins aren't
nearly as inefficient as what you seem to understand them as being. :)

It's just a matter of benchmarking to figure out where specifically your
problem lies.
