www.kaggle.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 14:02 UTC. Grade A (91/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 80 ms 29%
- TCP connect 33 ms 12%
- Server wait 166 ms 59%
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 279 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 1.17 MB over 13 request(s), which is lean. Javascript files are 98% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
- 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. 13 request(s) in total, 1.17 MB across all of them.
Top issues
Render-blocking resources
high impact6 render-blocking resource(s) in the document head (3 script(s), 3 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
medium impactThe page transfers 1.17 MB across 13 request(s), with the document itself at 2.3 KB.
Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.
JavaScript weight
medium impact1 JavaScript file(s) over 200 KB: vendor.js (999.4 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 impact1 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.
Third-party weight
low impact5 third-party host(s) serve 183.8 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.
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
