title: nodejs expressjs gzip json content
body: <p>I'm using express' res.end, etc to serve json as part of my rest api.</p>
  
  <p>Google pagespeed is telling me to gzip it.</p>
  
  <p>However according to this thread:</p>
  
  <p><a href="http://groups.google.com/group/express-js/browse_thread/thread/db1ad3307cb4f504/64f02170f616527c" rel="nofollow">http://groups.google.com/group/express-js/browse_thread/thread/db1ad3307cb4f504/64f02170f616527c</a></p>
  
  <p>it doesn't seem to be a good idea. After all that content is dynamic, and uncachable, so gzipping before every request doesn't seem like it'll be a net benefit.</p>
  
  <p>Am I right? Or should I pursue gzip, thanks.</p>
  
  <p>To be clear: static content (css, js) is already gzipped. </p>
