Vanity performance metrics — Looking beyond the numbers

Vanity performance metrics — Looking beyond the numbers

My deck from RuhrJS in Germany—Slide notes, references and Shoutouts to those who shared so much great and interesting data about global internet connectivity are missing! I'll attempt to update the deck in a couple of days after jetlag stops hurting me so much :-)

Shout out to Bruce Lawson for being such a thoughtful and clever person.

    light New York — Chicago
  5. 7200 Tweets 54,000 Google searches Every second on the internet

  6. 57% do not 43% have access

  7. How quickly will the 
 internet grow?

  8. The number of internet users in India will grow by

    100 million in 2016.
  9. Airtel, India’s largest mobile phone carrier has almost 250 million

    customers, but only a 32% market share.
  10. 65% of the 1.2 Billion population, do not have access

    to the internet today.
  11. Number of hours worked for 500mb of data India 17

    hrs Brazil 13 hrs Indonesia 6 hrs Germany <1 hr
  12. 1hr of work for: 8 songs on Spotify 6 minutes

    of Youtube Less than 1 hour playing online games.
  13. 3.7GB
 of data used to make this presentation

  14. Connections used Cable – 70mbps ADSL – 16mbps Plane wifi

    – 3mbps Phone tethering – 0—120mbps Hotel wifi – 1mbps
  15. Even if you’ve bought 500mb of data, and 4G is

    available, we cannot assume it will be 4G.
  16. Facebook Lite • 1mb to download • 1mb total footprint

    • Used by over

  21. The metrics that we’re using to talk about performance tell

    us nothing about the users.

  33. “I read a study that measured the efficiency of locomotion

    for various species on the planet. The condor used the least energy to move a kilometre. Humans came in with a rather unimpressive showing about a third of the way down the list....That didn't look so good, but then someone at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle and a man on a bicycle blew the condor away. That's what a computer is to me: the computer is the most remarkable tool that we've ever come up with. It's the equivalent of a bicycle for our minds.”
  34. A computer is the equivalent of bicycle for our minds.
