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 arrived in 214 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 367.7 KB over 26 request(s). Images files are 50% 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.
  • 50% 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 744 ms, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.018), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 1.39 s, so taps and scrolling wait while scripts run.

Fix first: Render-blocking resources - 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.

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 25 requests
182.9 KB 50%

Transfer size, compressed as sent. 26 request(s) in total, 367.7 KB across all of them.

Top issues

Render-blocking resources

high impact

9 render-blocking resource(s) in the document head (0 script(s), 9 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.

Cache static assets

medium impact

14 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.

HTML document size

medium impact

The document transfers 184.8 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
