I’m happy to say, for the metrics that matter the most, we are 700–1,200ms faster. On a high-latency connection, this spells bad news.

Along with other general diagnostics and web performance metrics, a really useful feature of the report is that each of the key areas is aggregated into color-coded scores between 0-100. To mitigate this issue, we’ll replace any colons with underscores ( _ ), so a typical report filename will look like: 2020-01-31T18_18_12.648Z.json.

Those two metrics are approximate indicators of failures and latency. When the threshold percentage for one of these two metrics is crossed, we reduce load on the service by throttling traffic. The key metrics used to trigger global throttling are CPU utilization, concurrent requests, and connection count.

Finally, not inlining resources has an added latency cost because the file needs to be requested. Relying only on high-level metrics is very dangerous because these could be skewed by a plethora of factors (such as unrealistic network emulation, a lack of features on clients or servers, only partial HTTP/3 usage, etc.).
