However, that pesky 20% on the back end can have a big impact on downstream metrics like First Contentful Paint (FCP), Largest Contentful Paint (LCP), and any other 'loading' metric you can think of. Charlie Vazac introduced server timing in a Performance Calendar post circa 2018. Also measured by round trip time (RTT).

For example, iostat(1), or a monitoring agent, may tell you your average disk latency, but not the distribution of this latency. bpftrace is suited for this kind of analysis: decomposing metrics into distributions or per-event logs, and creating new metrics for visibility into blind spots. 1 /* 2 * biolatency.bt

Existing systems can be studied with measurement, while prospective systems are most often studied by extrapolating from measurements of prior systems or via simulation software that mimics target system function and provides performance metrics. Can one both minimize latency and maximize throughput for unscheduled work? Little’s Law.

Today we are excited to announce latency heatmaps and improved container support for our on-host monitoring solution?—?Vector?—?to Remotely view real-time process scheduler latency and tcp throughput with Vector and eBPF What is Vector? to the broader community. Vector is open source and in use by multiple companies.

But do you know how Lighthouse calculates performance metrics like First Contentful Paint (FCP), Total Blocking Time (TBT), and Cumulative Layout Shift (CLS)? Still, there’s nothing in there to tell us about the data Lighthouse is using to evaluate metrics. But it comes with caveats. So why use lab data at all?

As mentioned in our earlier blog post , Intel and Netflix have been collaborating on the SVT-AV1 encoder and decoder framework since August 2018. In the plot, the Y-axis shows the additional bitrate in percent needed to achieve similar quality as libaom encoder according to three metrics. A single-threaded compression mode is used.

Site performance is potentially the most important metric. Google’s industry benchmarks from 2018 also provide a striking breakdown of how each second of loading affects bounce rates.
