sensic.net speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 13:20 UTC. Grade A (93/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 91 ms 36%
- TCP connect 41 ms 16%
- Server wait 123 ms 48%
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 255 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 277.1 KB over 9 request(s), which is lean. Images files are 76% of it, so resize and recompress the largest images before anything else.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- The largest element painted at 488 ms, inside the 2.5 s Google calls good.
- Layout stayed still (CLS 0.004), so nothing jumps under the reader's cursor.
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.
Screenshot
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, 277.1 KB across all of them.
Top issues
Compress text responses
high impact1 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 61.4 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 impact7 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.
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.
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
