www.browserstack.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 15:57 UTC. Grade A (95/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 69 ms 22%
- TCP connect 62 ms 20%
- Server wait 182 ms 58%
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 313 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 255.2 KB over 26 request(s).
- The HTML itself arrives gzip-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- 28% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
- The largest element painted at 736 ms, inside the 2.5 s Google calls good.
- The main thread was blocked for 117 ms in total, which is not enough to feel.
Fix first: TLS certificate validity - Renew automatically (certbot with a working renewal timer) and alert on the certificate, not on the renew command, so a silent failure is caught weeks before a browser warning.
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, 255.2 KB across all of them.
Top issues
TLS certificate validity
high impactThe certificate for www.browserstack.com has 16 day(s) left.
Fix: Renew automatically (certbot with a working renewal timer) and alert on the certificate, not on the renew command, so a silent failure is caught weeks before a browser warning.
HTML document size
medium impactThe document transfers 184.8 KB. A bloated document delays every other request, because nothing else can start until it is parsed.
Fix: Paginate long listings, move repeated markup into a template, and stop inlining large data URIs into the HTML.
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.
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
