  • Server wait 253 ms 66%

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 382 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 333.2 KB over 26 request(s). Images files are 94% of it, so resize and recompress the largest images before anything else.
  • The HTML itself arrives br-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • The largest element painted at 864 ms, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.025), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 46 ms in total, which is not enough to feel.

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.

Top issues

Render-blocking resources

high impact

3 render-blocking resource(s) in the document head (1 script(s), 2 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.

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
