caddyserver.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 15:36 UTC. Grade B (81/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 94 ms 29%
- TCP connect 61 ms 19%
- Server wait 175 ms 53%
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 329 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 113.5 KB over 26 request(s). Images files are 84% of it, so resize and recompress the largest images before anything else.
- The HTML itself arrives zstd-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- The largest element painted at 960 ms, inside the 2.5 s Google calls good.
- Layout shift is 0.231 (good is under 0.1): something without a reserved size is loading late - an image, an ad, or a font swap.
- The main thread was blocked for 197 ms in total, which is not enough to feel.
Fix first: Render-blocking resources - 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.
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. 26 request(s) in total, 113.5 KB across all of them.
Top issues
Render-blocking resources
high impact11 render-blocking resource(s) in the document head (4 script(s), 7 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 impact25 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
