Velocity 09: Eric Schurman and Jake Brutlag, "Performance Related Changes and their User Impact"

Posted in Conferences, Development on June 28, 2009



We took very small percentages of our users and slowed the page down in several ways

  • Added server side delays
  • Added additional page weight to different parts of our page
  • Added client side rendering delays

We then measured how each of these changes impacted metrics like clicks, time to click, repeat site usage, queries per visit, revenue, etc.

This talk is to share the results.
