cloudbirds.cn speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 14:39 UTC. Grade D (62/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 88 ms 6%
- TCP connect 200 ms 13%
- Server wait 1.29 s 82%
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 1.58 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 506.1 KB over 4 request(s), which is lean. Css files are 65% of it, so split the stylesheet so the first screen does not download the whole site.
- It runs over HTTP/2, so the assets share a connection instead of opening one each.
- The largest element took 4.91 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 80 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. 4 request(s) in total, 506.1 KB across all of them.
Top issues
Server response time (TTFB)
high impactThe first byte arrived after 1576 ms. Of that, 1288 ms was the server thinking and 288 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.
Compress text responses
high impact2 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 487.7 KB of compressible text.
Fix: Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.
Cache static assets
medium impact3 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.
Strict-Transport-Security
low impactHSTS is not set, so the first visit on a hostile network can still be downgraded to HTTP.
Fix: Send Strict-Transport-Security with a max-age of at least six months. Add includeSubDomains once every subdomain is HTTPS.
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
