The cool thing about D&#x27;s forums&#x2F;feed is how <i>amazingly fast</i> they are.  I wish more web apps were designed like this, with a fast backend framework.<p>Instead, it&#x27;s all either slow, slow backend frameworks like Ruby, or even worse, these SPA applications that require extensive client-side JS processing before they show you the goods.<p>Node is a step in the right direction for both problems: for the first, Node-based backend applications are faster than Ruby and Python, and for the client-side rendering problem, because Node can pre-render these SPA apps (which everyone should do for a serious production app that uses a framework&#x2F;library like AngularJS or React for major client-side rendering).<p>But a server application based on D or Rust, or even Go, is an even better solution to the slow backend framework issue.  Unfortunately, no one has yet created a full-service framework like Rails or Django for any of those languages.
