www.joom.com/en speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 14:06 UTC. Grade A (92/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 82 ms 20%
- TCP connect 34 ms 8%
- Server wait 299 ms 72%
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 415 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 323.5 KB over 11 request(s), which is lean. Javascript files are 99% 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.
- 99% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
- The largest element took 5.10 s to paint, past the 2.5 s threshold: usually a hero image that is too big or a render-blocking script in front of it.
- The main thread was blocked for 205 ms, so taps and scrolling wait while scripts run.
Fix first: Server response time (TTFB) - Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.
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.

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. 11 request(s) in total, 323.5 KB across all of them.
Top issues
Server response time (TTFB)
high impactThe first byte arrived after 415 ms. Of that, 299 ms was the server thinking and 116 ms was connection setup. A first byte under 400 ms is what a visitor feels as instant.
Fix: Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.
Third-party weight
medium impact2 third-party host(s) serve 321.4 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.
Avoid extra redirects
medium impact2 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.
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
