WPHost runs PHP 8.4. For typical WordPress PHP time, that beats almost every banner about “special WordPress caching” that still sits on an old runtime.
After that: a lean theme, fewer plugins, and a cache plugin you can explain. We do not operate a proprietary object cache or a built-in CDN. Put Cloudflare in front if you need a CDN; this host remains origin.
Staging on Pro plans exists so you can test that cache plugin before it surprises production.
