The measured traffic is not of your actual users; it is synthetically generated to collect data on page performance. As a result, users can identify latency and downtime promptly, and they can then scientifically isolate and diagnose the root cause of any performance issues that may arise.

3] As we'll see below, CPUs are not improving fast enough to cope with frontend engineers' rosy resource assumptions. Using a global ASP as a benchmark can further mislead thanks to the distorting effect of ultra-high-end prices rising while shipment volumes stagnate. Today, either method returns a similar answer.

Budgets are scaled to a benchmark network & device. We get a strong sense for how bad site performance is going to be based on the percentage of engineering leads, PMs, and decision makers carrying high-end phones which they primarily use in urban areas. Deciding what benchmark to use for a performance budget is crucial.
