In short
Measure visitor experience.Not a simulated promise.
Measurements from supported visitor browsers, split between mobile and desktop. This WordPress plugin measures; it is not a caching plugin and does not automatically speed up a site.
Four metrics side by side
LCP, INP and CLS sit beside TTFB, which is not itself a Core Web Vital. The source uses boundaries of 2.5/4 seconds, 200/500 milliseconds, 0.1/0.25 and 800/1800 milliseconds. The overview shows the 75th percentile, not the average.
Missing is not zero
By default a figure appears only after twenty measurements. A browser without support for a metric contributes nothing to it, not a perfect zero. Sample counts can therefore differ by metric.
Not the same as PageSpeed
Your own field measurements differ from a PageSpeed lab test and from Chrome User Experience Report data. This plugin does not optimise anything or diagnose a cause from four figures. Use the measurements to decide what needs closer investigation.
Boundaries around collection
The described table stores a page without query or anchor, metric, value, device class and rounded hour. No session ID or IP is kept in that table; rate limiting does use an address hash for at most a minute. DNT and GPC are respected by default, with 90-day default retention.
Configure, then collect enough evidence
Download version 1.0.0 is 51 KB, GPLv2 or later, for WordPress 6.0+ and PHP 7.4+. Collection goes to your own admin-ajax.php. Downloading or reading this page does not prove your site is already measuring, faster, or correctly configured for consent.
