www.ebooknetworking.net/ebooks/java.html speed test — 4 Nov 2026

What these numbers mean

• The server answered in 101 ms, which is fast: almost all of the wait is the page itself, not the host.
• The page transfers 374.0 KB over 26 request(s). Javascript files are 56% 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.
• 54% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
• The largest element painted at 340 ms, inside the 2.5 s Google calls good.
• Layout shift is 0.275 (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 221 ms, so taps and scrolling wait while scripts run.

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.
