ad-delivery.net speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 13:09 UTC. Grade A (96/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 65 ms 21%
- TCP connect 51 ms 17%
- Server wait 194 ms 63%
Measured on the connection that fetched the HTML. Every other request on the page waits for the end of this bar before it can start.
How this page compares
Every report published here is in this comparison, so it is a reference population of pages tested from one server - not a benchmark of the whole web.
What these numbers mean
- The first byte arrived in 309 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 454 B over 1 request(s), which is lean.
- The HTML itself arrives br-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- The largest element painted at 296 ms, inside the 2.5 s Google calls good.
Fix first: Mobile viewport - Add a viewport meta tag with width=device-width and an initial scale of 1.
Read on one shared server, not a visitor's phone: use it to compare pages against each other, not as a promise about every connection. We fix what these tests find.
Browser render
The same URL loaded in a real browser, so these are the readings curl cannot produce. The grade above is still built from the server measurements.
Top issues
Mobile viewport
medium impactNo viewport meta tag, so a phone renders the desktop layout scaled down.
Fix: Add a viewport meta tag with width=device-width and an initial scale of 1.
Strict-Transport-Security
low impactHSTS is not set, so the first visit on a hostile network can still be downgraded to HTTP.
Fix: Send Strict-Transport-Security with a max-age of at least six months. Add includeSubDomains once every subdomain is HTTPS.
