Darn, everyone always beats me to the punch!

This is sooo worth checking out if you haven't used it yet. My favorite tool for measuring the 'milliseconds till X' metric. The timeline view shows screenshots with times so you can figure out how long it takes to render above the fold.

How did pineapple do?

Really good, especially considering all of the images that are loading and the fact that the home page is constantly changing (harder to cache). On a cold cache, not averaged, 1.2s til first paint and last paint above the fold is ~2s. List view is much faster.

TCP windowing is a killer here too, lots of short reqs.

Some things that might shave off some time might be (using Chrome):

  • pull css onto a cdn (removing ~300 ms)
  • Inlining above the fold css to min. critical path
  • Cat the fonts into main css to save http req
  • Using varnish or something to speed up logged out requests (~400ms)
  • Defer favicon loading in favor of parallelizing important req's
  • Flush head early (Rails may already do this)

At any rate, i've never been like... this site is soooo slow lol.

I didn't notice it can simulate other browsers last time I checked this out, that's great.. in fact I was just trying to debug IE7 performance.

Steve Souders did a nice talk that featured it around 29mins:
