title: Greenrobot's EventBus performance drawbacks
body: <p>I have been using <a href="https://greenrobot.github.io/EventBus/" rel="nofollow">Greenrobot's Eventbus</a> for it's simplicity 
  for a while. I wonder if there is a performance loss if I use it in a scenario where I quite often post an event(4 times a second), and there is multiple recipients of the event, instead of using observer pattern.</p>
  
  <p>Any help will be much appreciated. Thanks</p>
