An Opinionated Guide to Performance Budgets

A performance budget is a threshold that you apply to the metrics you care about the most. Budgets are the best way to get fast and fight regression. But they’re one of those ideas that everyone gets behind conceptually, only to find them tricky to put into practice – and for very good reason. Web pages are unbelievably complex, and there are hundreds of potential performance metrics to track.

If you’re just getting started with performance budgets – or if you’ve been using them for a while and want to validate your work – this talk is for you.

Tammy will cover:

• Which metrics to focus on

• What your budget thresholds should be

• How to stay on top of your budgets
