Timing, with context
Timings come from this scanner’s network location. Repeat scans to distinguish persistent delays from normal variation. A quick HTML response does not guarantee a fast rendered page.
Scan your website’s performance
Measure your document’s response time and size, then review compression, redirects, and caching.
Just looking? Try the performance sample report — no website is contacted.
Smaller documents
Compare transferred and decoded document sizes. The scanner offers gzip and Brotli and checks how the server varies compressed responses for caches.
Cache appropriately
Caching advice considers private and no-store responses. Sensitive pages should stay private; performance should not compromise confidentiality.
