www.instructables.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 13:27 UTC. Grade A (91/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 86 ms 36%
- TCP connect 32 ms 13%
- Server wait 122 ms 51%
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 241 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 523.5 KB over 20 request(s). Fonts files are 42% of it, so subset the fonts and stop preloading the weights you do not render.
- The HTML itself arrives gzip-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- The largest element painted at 1.42 s, inside the 2.5 s Google calls good.
- Layout shift is 0.152 (good is under 0.1): something without a reserved size is loading late - an image, an ad, or a font swap.
- The main thread was blocked for 113 ms in total, which is not enough to feel.
Fix first: Compress text responses - Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.
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. 20 request(s) in total, 523.5 KB across all of them.
Top issues
Compress text responses
high impact1 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 11.7 KB of compressible text.
Fix: Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.
Render-blocking resources
high impact8 render-blocking resource(s) in the document head (2 script(s), 6 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.
Cache static assets
medium impact13 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.
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.
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
