Making Web faster

What makes it slow/ what can you improve upon

  • The ordering of data responded by server should be managed better, HTML first, then JS and then images…
  • DNS lookup is about 120 ms, consider that there would be n number of connections created by browser
  • SPDY – Pipelining, multiplexing, compression
  • Chrome : If you are using chrome then why should not the server be intelligent to support it? You could use apache mod for SPDY, ensure that you reuse HTTP connections
  • TCP Slow-Start *feature*, more info here, Faster Web vs. TCP Slow-Start – igvita.com
  • TCP cogestion control, http://tools.ietf.org/html/rfc5681
  • Test the speed of page here, webpagetest.org
