One could argue this is a metric-driven decision. When they dug into the data, they found that the reason load times had increased was that they got a lot more traffic from Africa after doing the optimizations. Lots of case studies where changes in performance led to key metric improvement. Well, not so fast.

On the other hand, when one is interested only in simple additive metrics like total page views or average price of conversion, it is obvious that raw data can be efficiently summarized, for example, on a daily basis or using simple in-stream counters. This opportunity is leveraged in the following case study. Case Study.

The best way to fight regressions is to create performance budgets on key metrics, and get alerted when they go out of bounds.

To hook different people on performance, you need to understand which metric motivates them. Case studies are a great way to convert performance skeptics.
