Eager LCP image
The hero image is intentionally oversized and rendered without fixed dimensions so the waterfall has a clear LCP candidate.
Slow WordPress install - Core Web Vitals lab
This private lab page is deliberately built to expose LCP, TTFB, render-blocking, asset delivery, and plugin-load problems using dummy content only.
The hero image is intentionally oversized and rendered without fixed dimensions so the waterfall has a clear LCP candidate.
Analytics, review, chat, cache, and DOM-noise stubs run everywhere even when the page does not need them.
Headers are intentionally weak, lazy loading is disabled, and extra fonts load without preload or display strategy.
Landing pages, guides, comparison sections, oversized graphics, and repeated below-fold image blocks.
Static UI labels only. There are no submissions, no live routes, and no monitored workflows in this lab.
Large DOM fragments and plugin widgets mimic overloaded production pages without using real customer data.
The slow state is intentional. It demonstrates typical WordPress Core Web Vitals mistakes in a controlled dummy install.
No. It is a technical lab using synthetic content and generated media.
No. Analytics, reviews, and chat are local stubs with no external network calls and no monitored routes.
Capture Lighthouse or PSI, network waterfall, LCP element, transfer size, request count, and response headers.
"The lab waterfall makes the oversized hero and plugin overhead easy to identify."
"Repeated global assets show how a page can stay slow even when the content looks simple."
"The same dummy content can be compared against a clean build without using client data."
