performance - Why does my 'dns' lookup and 'connect' take over 2 seconds (57% of page load time)? -

-

enter image description here

i found takes 2 seconds page display single thing (i'm assuming cause lookup taking longest) http://www.webpagetest.org/result/120613_qc_833b06d5bbdf38bafcff8ed2777be8ac/

how improve this, or rid of 2 second lag?

i hosting on heroku, , dns setup in godaddy.

dns not problem.

take closer @ network waterfall chart. application.js file first performance culprit. if can:

  • make smaller
  • if can, move script tag bottom of page
  • even better, if you're not doing document.write's in script, mark "async"

with out of way, background next biggest problem - it's massive. perhaps worth reconsidering if should there if you're concerned speed.
