Summary Evaluation of Velocity 2014:

  • The mobile share of internet traffic is on pace to eclipse desktop traffic within 2014. As a whole, developers are doing a poor job of optimizing for mobile and users are frustrated. Mobile sites are actually trending slower year over year, even with faster devices accounted for.
  • Even desktop performance affects business metrics (like conversion rate, bounce rate, page views, etc..). This can usually be measured without taking the time to optimize performance; most sites are serving a mixture of fast and slow experiences to users. Just correlate the metric vs performance while controlling for some variables (like location).
  • From Puppet's State of DevOps Report in 2014 - IT performance was qualified in a statistically valid way and highly correlated with these three independent metrics: MTTR (mean time to recover), lead time for chang
