Get in the Fast Lane: Measuring Web Performance

Get in the Fast Lane: Measuring Web Performance

Are you losing revenue to performance? 53% of mobile site visits are abandoned if a page takes longer than 3 seconds to load. Pinterest reduced load times by 40% and saw a 15% increase in sign ups. Starbucks implemented a 2x faster time to interactive resulting in a 65% increase in rewards registrations. AliExpress reduced load by 36% and saw a 10.5% increase in orders.

Performance is important. Tooling can be hard. Do flame charts intimidate you? Come learn how to audit and fix common performance issues using Chrome DevTools, Lighthouse, PageSpeed Insights, and webpagetest.org. During this hands-on, full-day workshop, you will learn how to:

  • Optimize and familiarize yourself with your DevTools environment
  • Understand which metrics matter
  • Measure the performance of existing applications
  • Diagnose and prioritize performance problems
