www.ezviz.com/cn speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 12:25 UTC. Grade E (55/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 51 ms 14%
- TCP connect 55 ms 15%
- Server wait 268 ms 71%
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 375 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 18.03 MB over 26 request(s). Media files are 90% of it, so let video load on demand instead of on first paint.
- The HTML itself arrives gzip-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- 100% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
- The largest element took 2.85 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 109 ms in total, which is not enough to feel.
Fix first: Compress text responses - 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.
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.
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, 18.03 MB across all of them.
Top issues
Compress text responses
high impact3 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 943.8 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.
Image delivery and format
high impact1 image(s) over 200 KB and 3 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.
Render-blocking resources
high impact5 render-blocking resource(s) in the document head (3 script(s), 2 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.
Total page weight
high impactThe page transfers 18.03 MB across 26 request(s), with the document itself at 15.5 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 18.01 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.
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
