login.gov speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 15:00 UTC. Grade A (98/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 87 ms 34%
- TCP connect 32 ms 13%
- Server wait 135 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 254 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 267.1 KB over 18 request(s). Javascript files are 71% 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.
- 66% 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 664 ms, inside the 2.5 s Google calls good.
- Layout stayed still (CLS 0.001), so nothing jumps under the reader's cursor.
- The main thread was blocked for 110 ms in total, which is not enough to feel.
Fix first: Cache static assets - Version filenames on change and serve them with a long max-age plus immutable. That is what makes a returning visitor fast.
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.

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. 18 request(s) in total, 267.1 KB across all of them.
Top issues
Cache static assets
medium impact1 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.
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
