title: Performance of AJAX vs Websocket REST over HTTP 2.0?
body: <p>What is the real-world performance difference between Websocket vs AJAX over HTTP 2.0?</p>
  
  <p>In particular, a project I'm working on requires bidirectional real-time updates, therefore, although nonstandard, if requests are only to be made within the domain, it may be more efficient to conduct REST over Websocket rather than AJAX.</p>
  
  <p>However, I'm not sure if currently available information regarding the performance differences hold true in the context of HTTP 2.0.</p>
