www.americanexpress.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 13:07 UTC. Grade A (90/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 84 ms 35%
- TCP connect 30 ms 13%
- Server wait 124 ms 52%
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 238 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 1.14 MB over 26 request(s). Javascript files are 78% 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.
- 83% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
Fix first: Total page weight - Work through the heaviest assets first: images, then fonts, then third-party scripts.
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.
The headless browser did not capture this page when the test ran, so only the server measurements are shown.
Page weight by type
What the page is made of
Transfer size, compressed as sent. 26 request(s) in total, 1.14 MB across all of them.
Top issues
Total page weight
medium impactThe page transfers 1.14 MB across 26 request(s), with the document itself at 104.2 KB.
Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.
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.
Third-party weight
medium impact1 third-party host(s) serve 969.1 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.
HTML document size
medium impactThe document transfers 104.2 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.
JavaScript weight
medium impact1 JavaScript file(s) over 200 KB: axp-homepage-us.browser.js (391.8 KB)
Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.
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
