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.

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 took 957 ms. Everything else waits for that number, so the server is where to start: caching, a slow query, or an overloaded host.
  • The page transfers 475.3 KB over 14 request(s), which is lean. Javascript files are 62% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
  • The HTML itself arrives gzip-compressed.
  • It runs over HTTP/2, so the assets share a connection instead of opening one each.
  • 42% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
  • The largest element painted at 1.94 s, inside the 2.5 s Google calls good.
  • The main thread was blocked for 8 ms in total, which is not enough to feel.

Fix first: Server response time (TTFB) - Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.

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.

Top issues

Server response time (TTFB)

high impact

The first byte arrived after 957 ms. Of that, 587 ms was the server thinking and 370 ms was connection setup. A first byte under 400 ms is what a visitor feels as instant.

Fix: Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.

Compress text responses

high impact

3 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 301.9 KB of compressible text.

Fix: Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.

Render-blocking resources

high impact

3 render-blocking resource(s) in the document head (2 script(s), 1 stylesheet(s)). The page cannot paint until each one arrives.

Fix: Add defer or async to scripts that do not change the first paint, inline the critical CSS, and load the rest with media="print" plus an onload swap.

JavaScript weight

medium impact

1 JavaScript file(s) over 200 KB: adsbygoogle.js (201.1 KB)

Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.

Strict-Transport-Security

low impact

HSTS 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.

Each bar is one request's own response time, scaled to the slowest. Assets were fetched in parallel, so the bars overlap in real time rather than stacking. first party third party
