www.uptodown.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 14:49 UTC. Grade D (64/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 56 ms 3%
- TCP connect 27 ms 1%
- Server wait 1.94 s 96%
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 took 2.02 s. Everything else waits for that number, so the server is where to start: caching, a slow query, or an overloaded host.
- The page transfers 693.8 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.
- 94% 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 508 ms, inside the 2.5 s Google calls good.
- Layout shift is 0.172 (good is under 0.1): something without a reserved size is loading late - an image, an ad, or a font swap.
- The main thread was blocked for 30 ms in total, which is not enough to feel.
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. 26 request(s) in total, 693.8 KB across all of them.
Top issues
Server response time (TTFB)
high impactThe first byte arrived after 2020 ms. Of that, 1937 ms was the server thinking and 83 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.
Render-blocking resources
high impact4 render-blocking resource(s) in the document head (0 script(s), 4 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.
TLS certificate validity
high impactThe certificate for www.uptodown.com has 12 day(s) left.
Fix: Renew automatically (certbot with a working renewal timer) and alert on the certificate, not on the renew command, so a silent failure is caught weeks before a browser warning.
Third-party weight
medium impact2 third-party host(s) serve 653.6 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 impact1 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
