mamastar.jp speed test — 20 Oct 2026

The first byte arrived after 1053 ms. Of that, 903 ms was the server thinking and 150 ms was connection setup. A first byte under 400 ms is what a visitor feels as instant.

Fix: Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.

0 text response(s) of 10 KB or more are sent uncompressed, and the document itself is compressed. That is 0 B 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.

12 image(s) over 200 KB and 18 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.

11 render-blocking resource(s) in the document head (4 script(s), 7 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.

The page transfers 6.65 MB across 26 request(s), with the document itself at 94.9 KB.

Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.
