title: HTTP/2 or Websockets for low latency client to server messages
body: <p>I have a requirement to have very low latency for client to server messages in my web application.</p>
  
  <p>I have seen several posts on stackoverflow saying it would be preferable to use websockets instead of HTTP for this requirement, but it was quite some time ago.</p>
  
  <p>Today, in 2018, with the progress of HTTP/2, is it still worth using websockets for this use case ? </p>
