Where the first byte went

  • DNS lookup 59 ms 24%
  • TCP connect 47 ms 19%
  • Server wait 141 ms 57%

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 247 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 17.5 KB over 2 request(s), which is lean. Images files are 93% of it, so resize and recompress the largest images before anything else.
  • The HTML itself arrives gzip-compressed.
  • It runs over HTTP/2, so the assets share a connection instead of opening one each.
  • The largest element painted at 192 ms, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.066), so nothing jumps under the reader's cursor.

Fix first: Mobile viewport - Add a viewport meta tag with width=device-width and an initial scale of 1.

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

Mobile viewport

medium impact

No viewport meta tag, so a phone renders the desktop layout scaled down.

Fix: Add a viewport meta tag with width=device-width and an initial scale of 1.

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
