But do you know how Lighthouse calculates performance metrics like First Contentful Paint (FCP), Total Blocking Time (TBT), and Cumulative Layout Shift (CLS)? There’s a handy calculator linked up in the report summary that lets you adjust performance values to see how they impact the overall score. But it comes with caveats.

Many people often confuse site speed with page speed grades of performance testing tools, which are actually calculated based on multiple factors of a page including its loading speed. Core web vitals are modern performance metrics that analyze page speed signals that are crucial to providing a superior web experience.

Cache-Headers missing? These heuristics were coupled with a set of guidelines that would likely result in better performance, if followed, but were merely superficial and didn’t actually analyze the load and render experience that real visitors face. Guidelines for improvement are suggested based on how specific metrics score.

This can turn a 1% overhead (syscall cycles alone) into a 7% overhead.

Stable media is commonly physical disk storage, but other devices and certain caching facilities qualify as well. Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. This cache is often supported by a battery-powered backup facility.

This approach was touted to be better for fine-grained caching because each subresource could be cached individually and the full bundle didn’t need to be redownloaded if one of them changed. Upon receipt of a valid Alt-Svc header indicating HTTP/3 support, the browser will cache this and try to set up a QUIC connection from then on.
