tailwindcss.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 14:22 UTC. Grade C (74/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 56 ms 18%
- TCP connect 49 ms 16%
- Server wait 209 ms 67%
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 314 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 4.21 MB over 26 request(s). Images files are 97% 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.
- The largest element painted at 656 ms, inside the 2.5 s Google calls good.
- The main thread was blocked for 171 ms in total, which is not enough to feel.
Fix first: Image delivery and format - 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.
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, 4.21 MB across all of them.
Top issues
Image delivery and format
high impact8 image(s) over 200 KB and 14 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.
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.
Total page weight
high impactThe page transfers 4.21 MB across 26 request(s), with the document itself at 120.7 KB.
Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.
HTML document size
medium impactThe document transfers 120.7 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
