Competitive Benchmark
How fast the Homepage, Search, a product listing and a product detail page get content above the fold, across the competitive set, at High, Medium and Low bandwidth, as a guest and signed in.

One line per site. Lower is better for every timing metric.

Above The Fold (ATF) is the time the viewport first settled: the first filmstrip frame after first paint that is followed by at least a second of visually stable frames. A signup modal or carousel that fires later does not move it. It is the number this site is built around. Sources differ in how finely they resolve it, so every ATF value carries a precision, shown as a plus or minus in the detail view.
Speed Index, LCP, FCP, TTFB, TBT, TTI and CLS are the standard Lighthouse lab metrics. Field metrics are Chrome UX Report p75 values from real Chrome users over the last 28 days, when Google has enough traffic for the URL or its origin.
| High | Unthrottled desktop, no CPU slowdown |
| Medium | 9 Mbps down, 1.5 Mbps up, 170 ms RTT, 2x CPU slowdown (Lighthouse 4G) |
| Low | 1.6 Mbps down, 750 Kbps up, 150 ms RTT, 4x CPU slowdown (Lighthouse Slow 4G) |
PSI: Google PageSpeed Insights runs Lighthouse on Google's machines. It supplies the Low tier (mobile) and the High tier (desktop), plus field data. Playwright: our own collector drives Chromium with network emulation and a screencast; it supplies the Medium tier and a fine-grained ATF. Browsertime: sitespeed.io's Visual Metrics, when a run posts them.
A cell marked with a flag had very few requests and bytes, which usually means a bot wall answered instead of the page. Treat it as unmeasured.
