Overall #6 sevenpx.design #1 · 30 measurements · since Jul 7, 2026

The measuring machine was faster than usual.

Lighthouse benchmark index was 2985 against a baseline of 2478 (21%). CPU-bound metrics — TBT, TTI, main thread work — are affected by this and may have moved without the site changing at all.

Stack

Detected on the same page load as the accessibility pass — the generator from <meta name="generator"> or the shape of the page, the host from response headers.

Filmstrip Lighthouse, mobile

How the page drew during the measured load, at 8 points across 3.00 s.

Without JavaScript

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

Scripts disabled
As rendered

12.1% of pixels differ — parts of the page change. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.

What LCP is made of observed, unthrottled

A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Measured on the trace before throttling is modelled, so these are real durations that will not sum to the 3.94 s above — that figure is a simulation of the same load on a slow phone and connection. Read these for the proportions: which phase dominates.

Axe violations axe-core 4.13.0, full rule set

0 violating nodes across 0 rules, 66 passing. This is a standalone axe run, stricter than the subset Lighthouse folds into its score above — and it is the second tiebreaker in the ranking.
