Performance in 2012 Performance bottlenecks have moved from the backend to the frontend © 2012 Torbit 3
Problem Limitations of synthetic testing (active monitoring) Limited visibility Expensive Strains the systems you are testing Limited test locations and browsers Backbone connections paint an overly optimistic picture Can be easily gamed by CDNs or other providers © 2012 Torbit 4
Problem Website performance is viewed as a technical metric instead of a business metric © 2012 Torbit 5
A better idea Real User Measurement Use JavaScript to measure every visitor on every page and correlate how site performance impacts the business metrics you care about most © 2012 Torbit 6
