Where the first byte went

  • DNS lookup 66 ms 21%
  • TCP connect 53 ms 17%
  • Server wait 189 ms 61%

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

First bytefaster than 73% of 4,999 pages tested here308 ms against a median of 449 ms
Page weightlighter than 78% of 4,999 pages tested here229.0 KB against a median of 650.5 KB
Fully loadedslower than 55% of 4,999 pages tested here1.96 s against a median of 1.84 s
Requestssends fewer requests than 76% of 4,999 pages tested here24 against a median of 26

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 308 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 229.0 KB over 24 request(s). Javascript files are 63% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
  • The HTML itself arrives br-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • 99% 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 664 ms, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.003), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 20 ms in total, which is not enough to feel.

Fix first: Cache static assets - Version filenames on change and serve them with a long max-age plus immutable. That is what makes a returning visitor fast.

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

Cache static assets

medium impact

20 asset(s) answer without a Cache-Control max-age, so browsers revalidate them on every visit.

Fix: Version filenames on change and serve them with a long max-age plus immutable. That is what makes a returning visitor fast.

Avoid extra redirects

medium impact

1 redirect hop(s) before the page load started, each one a full round trip before the first byte.

Fix: Link to the canonical URL (and make sure http, the apex domain and www all point at it) so no visitor pays a redirect first.

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
