Web Performance is important for user experience and business metrics. This post explains several ways of assessing the potential performance gains with little effort and, more importantly, without actually implementing fixes. What is the business opportunity for web performance improvements? I would repeat over and over.

The best way to fight regressions is to create performance budgets on key metrics, and get alerted when they go out of bounds. You can even go one step further and integrate your performance budgets with your CI/CD process, so that you not only get alerts but even break the build if a new deploy would violate any of your budgets.
