bj.58.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 14:09 UTC. Grade B (81/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 71 ms 9%
- TCP connect 234 ms 29%
- Server wait 514 ms 63%
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 819 ms. Everything else waits for that number, so the server is where to start: caching, a slow query, or an overloaded host.
- The page transfers 103.5 KB over 9 request(s), which is lean. Images files are 64% 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.
- 79% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
- The largest element took 6.88 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.
- Layout stayed still (CLS 0.014), so nothing jumps under the reader's cursor.
- The main thread was blocked for 513 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. 9 request(s) in total, 103.5 KB across all of them.
Top issues
Server response time (TTFB)
high impactThe first byte arrived after 819 ms. Of that, 514 ms was the server thinking and 305 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 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.
Cache static assets
medium impact4 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.
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.
Mobile viewport
medium impactNo viewport meta tag, so a phone renders the desktop layout scaled down.
Fix: Add a viewport meta tag with width=device-width and an initial scale of 1.
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
