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. This allows us to process the report later without resulting in a messy pyramid of JavaScript. Here’s what a full report looks like.

Already in the 2000s, service-oriented architectures (SOA) became popular, and operations teams discovered the need to understand how transactions traverse through all tiers and how these tiers contributed to the execution time and latency. In 2019, the OpenCensus and OpenTracing projects merged into what we now know as OpenTelemetry.

Without beating around the bush, our ASP 2019 device was an Android that cost between $300-$350, new and unlocked. These devices feature: Eight slow, big.LITTLE ARM cores (A75+A55, or A73+A53) built on last-generation processes with very little cache. Still, until we pull into that station, per-page-load metrics are useful.

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. Two failure modes we focus on are a service becoming slower (increase in response latency) or a service failing outright (returning errors).

Having released this functionality in an Preview Release back in September 2019, we’re now happy to announce the General Availability of our Citrix monitoring extension. All processes on these hosts are recognized, and Citrix processes are grouped together in order to characterize the combined Citrix overhead on the infrastructure.

The scale of the effect can be deeply situational or hard to suss out without solid metrics. Since then, the metrics conversation has moved forward significantly, culminating in Core Web Vitals , reported via the Chrome User Experience Report to reflect the real-world experiences of users.

Updates on 2019-01-23 in blue. When running a single user thread, you will often get the advertised single-core Turbo frequency, but if the operating system enables more cores to handle (even very short-lived) background processes, your frequency may drop unexpectedly. RDTSCP can still be executed later than expected, but not earlier.

Key user-centric metrics often depend on the size, number, layout, and loading priority of images on the page. Smaller file size directly impacts the Largest contentful Paint (LCP) metric for the page as image resources needed by the page get loaded faster. A complex decoding process can slow down the rendering of images.
