Where the first byte went

  • DNS lookup 89 ms 23%
  • TCP connect 11 ms 3%
  • Server wait 284 ms 74%

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

Page weightheavier than 80% of 4,999 pages tested here1.88 MB against a median of 650.3 KB

Requestssends more requests than 100% of 4,999 pages tested here26 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 384 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 1.88 MB over 26 request(s). Images files are 62% of it, so resize and recompress the largest images before anything else.
  • The HTML itself arrives gzip-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • 88% 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 672 ms, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.006), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 913 ms, so taps and scrolling wait while scripts run.

Fix first: Compress text responses - 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.

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.

Page weight by type

What the page is made of

Images 21 requests

Javascript 4 requests
506.8 KB 26%

Transfer size, compressed as sent. 26 request(s) in total, 1.88 MB across all of them.

Top issues

Compress text responses

high impact

1 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 131.4 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.

Total page weight

high impact

The page transfers 1.88 MB across 26 request(s), with the document itself at 221.9 KB.

Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.

Image delivery and format

medium impact

0 image(s) over 200 KB and 2 large image(s) still served as JPEG or PNG.

Fix: Serve WebP or AVIF with a JPEG fallback, size images to the space they occupy, and lazy-load anything below the fold. Images are usually more than half of a slow page.

Cache static assets

medium impact

5 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.

Third-party weight

medium impact

12 third-party host(s) serve 1.66 MB of this page. Each one is another DNS lookup, TLS handshake and point of failure you do not control.

Fix: Self-host the libraries you can, drop the tags you cannot justify, and preconnect the ones you keep.
