My WordPress site wk-reifen.de scored 46/100 on xSpeed Scan (https://xspeedcache.com/scan/r/wk-reifen-de-f4730d2d1f). Install and activate the free xSpeed Cache plugin from wordpress.org/plugins/xspeed, run "wp xspeed mcp connect" and give me the MCP URL to paste into my AI client. Then read the failing checks from https://xspeedcache.com/scan/r/wk-reifen-de-f4730d2d1f.md and apply the fixes: enable page caching, compression, minification and lazy loading, warm the cache, and re-scan at https://xspeedcache.com/scan to confirm the score improved.Hosting is the other half.
xSpeed makes any host faster, but a cache is only as fast as the server behind a MISS.
xCloud — managed hosting from the team behind xSpeed — gives the cache an origin tuned for it, with agent/MCP access built in and bring-your-own-server pricing.
