ilya.grigorik.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 14:44 UTC. Grade A (93/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 64 ms 25%
- TCP connect 47 ms 19%
- Server wait 143 ms 56%
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 254 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 816.0 KB over 12 request(s), which is lean. Javascript files are 96% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
- The HTML itself arrives gzip-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- 88% 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 1.04 s, inside the 2.5 s Google calls good.
- Layout stayed still (CLS 0.041), so nothing jumps under the reader's cursor.
- The main thread was blocked for 51 ms in total, which is not enough to feel.
Fix first: Third-party weight - Self-host the libraries you can, drop the tags you cannot justify, and preconnect the ones you keep.
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. 12 request(s) in total, 816.0 KB across all of them.
Top issues
Third-party weight
medium impact4 third-party host(s) serve 719.8 KB 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.
JavaScript weight
medium impact1 JavaScript file(s) over 200 KB: portal.min.js (494.7 KB)
Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.
Avoid extra redirects
medium impact2 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.
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
