As a performance engineer, one of the first shifts in thought is that we don’t care only about when resources were discovered or requests were dispatched (the leftmost part of each entry). Of course, a late-discovered file will also be late-useful, but really the only thing that matters is usefulness.

To accomplish this goal, an organization needs to build internal processes and procedures that can operationalize a performance-first culture. The first step is to establish and implement web performance budgets.
