www.dingtalk.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 13:40 UTC. Grade D (62/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 287 ms 19%
- TCP connect 102 ms 7%
- Server wait 1.15 s 75%
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 1.54 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 1.36 MB over 9 request(s), which is lean. Images files are 99% of it, so resize and recompress the largest images before anything else.
- The HTML itself arrives gzip-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.
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.
The headless browser did not capture this page when the test ran, so only the server measurements are shown.
Page weight by type
What the page is made of
Transfer size, compressed as sent. 9 request(s) in total, 1.36 MB across all of them.
Top issues
Server response time (TTFB)
high impactThe first byte arrived after 1536 ms. Of that, 1147 ms was the server thinking and 389 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.
Image delivery and format
high impact1 image(s) over 200 KB and 1 large image(s) still served as JPEG or PNG.
Fix: Serve WebP or AVIF with a JPEG fallback, size images to the space they occupy, and lazy-load anything below the fold. Images are usually more than half of a slow page.
Total page weight
medium impactThe page transfers 1.36 MB across 9 request(s), with the document itself at 12.2 KB.
Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.
Third-party weight
medium impact3 third-party host(s) serve 1.35 MB 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
