Performance Budgets for the Real World

Performance budgets have been around for more than ten years. Over those years, we’ve learned a lot about what works, what doesn’t, and what we need to improve. In this session, Tammy revisits old assumptions about performance budgets and offers some new best practices. Topics include:

  • Understanding performance budgets vs. performance goals
  • Aligning budgets with user experience
  • Pros and cons of Core Web Vitals
  • How to stay on top of your budgets to fight regressions
