www.pandora.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 12:40 UTC. Grade B (88/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 53 ms 17%
- TCP connect 45 ms 14%
- Server wait 219 ms 69%
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
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 317 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 986.6 KB over 13 request(s), which is lean. Javascript files are 95% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
- The HTML itself arrives gzip-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- 97% 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 1.48 s, inside the 2.5 s Google calls good.
- The main thread was blocked for 105 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.
Screenshot
What the page looks like
Loaded in headless Chromium on this server. Click an image to open it full size.
Browser render
The same URL loaded in a real browser, so these are the readings curl cannot produce. The grade above is still built from the server measurements.
Page weight by type
What the page is made of
Transfer size, compressed as sent. 13 request(s) in total, 986.6 KB across all of them.
Top issues
Render-blocking resources
high impact3 render-blocking resource(s) in the document head (0 script(s), 3 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.
Total page weight
medium impactThe page transfers 986.6 KB across 13 request(s), with the document itself at 7.6 KB.
Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.
Cache static assets
medium impact1 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.
Third-party weight
medium impact2 third-party host(s) serve 956.5 KB of this page. Each one is another DNS lookup, TLS handshake and point of failure you do not control.
Fix: Self-host the libraries you can, drop the tags you cannot justify, and preconnect the ones you keep.
JavaScript weight
medium impact2 JavaScript file(s) over 200 KB: web-app.c532b8d045d20ffdc585.js (338.0 KB), web-vendor.5d5f212723e8e4de1e54.js (399.8 KB)
Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.
Waterfall
Slowest requests
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
