www.home-assistant.io speed test — 20 Oct 2026

What these numbers mean

• The first byte arrived in 330 ms. That is workable, and the cheapest win left is caching or a warmer connection.
• The page transfers 240.0 KB over 26 request(s). Images files are 85% 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 636 ms, inside the 2.5 s Google calls good.
• Layout stayed still (CLS 0.005), so nothing jumps under the reader's cursor.
• The main thread was blocked for 77 ms in total, which is not enough to feel.

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.
