title: Fullcalendar rendering 2000 events
body: <p>I've a fullcalendar script running but I need to render about 2000 to 3000 events.</p>
  
  <p>I already <a href="https://stackoverflow.com/questions/8313953/very-slow-loading-calendar-events-any-way-to-optimize">read this post</a> and I've done that (Only load the events between start and end date). Then I've made the JSON call so that Javascript only have to send it to fullcalender. Also, I don't use renderEvent.</p>
  
  <p>But the rendering of the events is still very slow. The ajax call takes about 400 milliseconds after the successful call the browser is taking about 5 to 10 seconds to render all the events. </p>
  
  <p>Where else can I gain speed?</p>
