Web Performance That Matters

Mike PetrovichFor web applications that are JavaScript- and AJAX-heavy, DOM Ready and Page Load timings are not accurate metrics for evaluating the actual performance of the end-user experience.

We introduce a new metric, "user-ready time", that correlates more closely with how real users experience a web application. By following a scientific method of hypothesis, testing, and analysis, we have been able to strongly correlate our performance gains to key business metrics.

Mike Petrovich (@mikepetrovich) leads front-end engineering of AYI.com at SNAP Interactive and is a contributor to jQuery, jQuery UI, and Handlebars.js.

As always, Animoto provides food and drinks and we'll have our geek-away raffles sponsored by Catchpoint and O'Reilly!

    Damn, probably doing a mixer around that time. Would've loved to attend the NY version of LAWebSpeed while I'm here.
