trezor.io speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 15:37 UTC. Grade A (95/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 76 ms 31%
- TCP connect 40 ms 16%
- Server wait 129 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 245 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 447.5 KB over 26 request(s). Images files are 60% of it, so resize and recompress the largest images before anything else.
- The HTML itself arrives br-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
Fix first: Render-blocking resources - Add defer or async to scripts that do not change the first paint, inline the critical CSS, and load the rest with media="print" plus an onload swap.
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, 447.5 KB across all of them.
Top issues
Render-blocking resources
high impact3 render-blocking resource(s) in the document head (1 script(s), 2 stylesheet(s)). The page cannot paint until each one arrives.
Fix: Add defer or async to scripts that do not change the first paint, inline the critical CSS, and load the rest with media="print" plus an onload swap.
Image delivery and format
medium impact0 image(s) over 200 KB and 1 large image(s) still served as JPEG or PNG.
Fix: Serve WebP or AVIF with a JPEG fallback, size images to the space they occupy, and lazy-load anything below the fold. Images are usually more than half of a slow page.
HTML document size
medium impactThe document transfers 177.6 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.
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
