Moreover, just like an A/B test, we’ll be collecting metrics while the experiment is underway and performing statistical analysis at the end to interpret the results.

Google Lighthouse is one of the best-automated tools available on a web developer's utility belt. 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. But first, for the uninitiated. Let’s find out how.

Updates on 2019-01-23 in blue. This partial ordering can help expose the execution time of long-latency instructions (such as memory accesses or mispredicted branches) that occur shortly before the final value of the TSC is read using RDTSCP. There are lots of topics that you need to be aware of when attempting fine-grain timing.

The computation is done as a first step so that it is available for the rest of the request lifecycle. 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.
