2osb.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 14:55 UTC. Grade A (94/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 63 ms 16%
- TCP connect 40 ms 10%
- Server wait 298 ms 74%
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 401 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 43.1 KB over 11 request(s), which is lean. Images files are 83% 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 596 ms, inside the 2.5 s Google calls good.
- Layout shift is 0.164 (good is under 0.1): something without a reserved size is loading late - an image, an ad, or a font swap.
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.
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. 11 request(s) in total, 43.1 KB across all of them.
Top issues
Server response time (TTFB)
high impactThe first byte arrived after 401 ms. Of that, 298 ms was the server thinking and 103 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.
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
