Where the first byte went

  • TCP connect 23 ms 10%
  • Server wait 132 ms 55%

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 240 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 438.0 KB over 26 request(s). Javascript files are 55% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
  • 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 1.48 s, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.012), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 402 ms, 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.

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.

Cache static assets

medium impact

10 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 163.7 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.

JavaScript weight

medium impact

1 JavaScript file(s) over 200 KB: jdOCsoUa.js (241.5 KB)

Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.

Avoid extra redirects

medium impact

1 redirect hop(s) before the page load started, each one a full round trip before the first byte.

Fix: Link to the canonical URL (and make sure http, the apex domain and www all point at it) so no visitor pays a redirect first.

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
