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 weightlighter than 81% of 4,999 pages tested here174.5 KB against a median of 650.5 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 258 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 174.5 KB over 26 request(s).
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • 21% 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 740 ms, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.002), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 102 ms in total, which is not enough to feel.

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.

What the page is made of

Images 25 requests
36.9 KB 21%

Transfer size, compressed as sent. 26 request(s) in total, 174.5 KB across all of them.

Top issues

Compress text responses

high impact

0 text response(s) of 10 KB or more are sent uncompressed, and the document itself is compressed. That is 0 B 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

17 render-blocking resource(s) in the document head (10 script(s), 7 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.

HTML document size

medium impact

The document transfers 137.6 KB. A bloated document delays every other request, because nothing else can start until it is parsed.

Fix: Paginate long listings, move repeated markup into a template, and stop inlining large data URIs into the HTML.

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
