Page Speed

Benchmark any URL like a pro: load times from the probe you choose, a clear performance grade, resource stats (including image & asset timing), and smart suggestions to make your pages faster.

How we measure

Probe location — Pick a mirror next to Test. We request your page once from that location and report DNS, connect, time to first byte (TTFB), and full load for that probe. The score is derived from that full load; letter grades run from A (90+) through F.

Resource insights — From this app server we fetch the HTML and a sample of linked assets (scripts, styles, images, and more) to show weight, mix by type and domain, per-request timings, and caching hints (no full browser / no JS execution). Preview uses WordPress mshots first, then Microlink or og:image when needed.

Fair use & speed — Parallel runs are capped (with extra headroom when the host is idle). Your browser may wait in a queue with position and total depth. Slots from crashed PHP workers expire after ~12 minutes so the line doesn’t stall forever. Starting a test vs queue polling use separate per-IP rate limits. Identical URL + probe may return from cache. If the queue is full or you’re rate-limited, we may show the last saved report when available.
