详情介绍:
- With xSpeed static cache: 5 to 15ms response time
- Without it (PHP-served cache): around 85ms response time
- Set up an AI connection from the MCP card on the Overview
- Read-only connections can read status, while write actions stay refused
- An AI assistant cannot write credentials unless you grant that permission when connecting
- WP-CLI parity:
wp xspeed purge,wp xspeed preloader status,wp xspeed score run,wp xspeed optimizeandwp xspeed settings list|get|update - The
optimize_sitetool measures the site, applies recommended settings one at a time, re-checks the page after each change and reverts anything that breaks it
- Disable dashicons on the frontend
- Remove oEmbed, RSS feeds, XML-RPC, jQuery Migrate and REST API authentication headers
- Static-file rewrite path that bypasses PHP entirely for a 5 to 15ms TTFB
- Auto-purge on publish, update, comment and theme change
- One-click cache purge from the admin bar
- Exclude specific URLs such as
/cart,/checkoutand/my-account - Set your own cache expiry, from 1 to 720 hours
- Separate mobile cache for phone and tablet visitors
- Per-post cache rules with custom expiry, or disable caching for individual posts
- Minify HTML, CSS and JavaScript
- Combine CSS and JS files to reduce HTTP requests
- Defer or delay JavaScript so it does not block page rendering
- Async CSS loading
- Removes
?ver=query strings from asset URLs (generated files underwp-content/uploadskeep theirs, so a page-builder or consent-banner edit still reaches returning visitors) - Safe-minify skips already-minified files and falls back if anything looks off
- Auto-configures GZIP on Apache and LiteSpeed
- Shows a ready-to-paste config snippet for nginx and IIS
- Detects if your server already has GZIP active, so there is no double-configuration
- Lazy load images, iframes and videos so they load when a visitor scrolls to them
- Adds missing image sizes so the layout does not jump
- Adds
font-display: swapso text is visible immediately while fonts load - Preloads above-the-fold font files
- Removes the blank-text flash caused by slow Google Fonts responses
- Sets
Cache-ControlandExpiresheaders for images, CSS and JS, with no manual configuration
- Sitemap-driven cache warmer, so the first visitor after a purge still gets a fast page
- Auto-warms the cache when you publish or update content
- Connect Redis or Memcached in seconds, as a drop-in persistent object cache
- View status and flush the object cache from the dashboard
- Pull-zone URL rewriting for any CDN provider
- Cloudflare integration: connect your zone, auto-purge on publish and toggle development mode
- Optimize database tables
- Remove post revisions, spam, trash, transients and orphaned meta
- Schedule automatic cleanup
- Multisite ready. Each site in the network gets its own cache and settings.
- LiteSpeed server? xSpeed Cache also clears the server's LiteSpeed cache whenever it clears its own. If the LiteSpeed Cache plugin is active, xSpeed Cache will not turn on its own page cache or the other features that overlap, so the two never run at once.
- WooCommerce? Logged-in customers and checkout pages are never cached.
- WordPress Site Health. xSpeed Cache adds its own check under Tools → Site Health.
- Works on any server. Apache, nginx, LiteSpeed, IIS and any standard PHP host.
/wp-json/xspeed/v1/, developer filters (xspeed_skip_minify, xspeed_strip_asset_version, xspeed_cache_skip_for_post, xspeed_cache_expiry_for_post), WP_DEBUG awareness, and a React 18 and TypeScript admin UI.
Agencies: Use the xspeed_branding filter to white-label the dashboard for clients.
Private By Default
xSpeed Cache stores no IP addresses and sets no tracking cookies. Out of the box, the only request it makes is a check to your own site's home URL to confirm GZIP is active, at most once an hour.
Usage analytics is optional and off by default. If you turn it on in the setup wizard or in xSpeed Cache → Settings → Privacy & usage data, it sends your email address and display name, your site's setup and which xSpeed Cache features you use. Page content is never sent. See the External services section below for every service the plugin can contact.
If xSpeed Cache makes your site faster, please leave a review on WordPress.org.
安装:
- Upload the
xspeedfolder to the/wp-content/plugins/directory, or install the plugin through the WordPress Plugins screen directly. - Activate the plugin through the Plugins screen in WordPress.
- Open xSpeed Cache from the admin menu. The 3-step setup wizard walks you through first-time configuration in under 2 minutes.
- Settings auto-save, so there is no Save button to forget.

常见问题:
Does this WordPress cache plugin work on my server?
Yes. xSpeed Cache works on Apache, nginx, LiteSpeed, IIS and any standard PHP host. GZIP auto-configures on Apache and LiteSpeed, and a ready-to-paste config snippet is provided for nginx and IIS.
Will it conflict with LiteSpeed Cache?
No. xSpeed Cache detects the LiteSpeed Cache server module and steps back to avoid conflicts.
Is it safe for WooCommerce?
Yes. Logged-in customers and checkout pages are never cached, and you can exclude specific URLs such as /cart, /checkout and /my-account.
Does it support multisite?
Yes. Each site in the network gets its own cache and settings.
Is this a WordPress MCP adapter?
Not exactly. A WordPress MCP adapter usually exposes core WordPress data. The xSpeed Cache MCP server exposes the performance tools this plugin owns, such as cache purging, preloader status, score runs and settings reads and writes, so an assistant works on speed rather than on content.
Can I connect Claude to it?
Yes. A WordPress MCP Claude connection uses OAuth discovery, and the MCP server appears on the Overview as a capability card so you can set it up without hunting for a panel. Read-only connections stay read-only.
Is xSpeed Cache the best free WordPress cache plugin?
That is for you to judge, but here is the honest basis for comparison. The static-file rewrite path serves cached pages before PHP loads, across Apache, nginx and LiteSpeed, which most free plugins do not do. Object caching, CDN support and database cleanup are included rather than reserved for a paid tier.
Can it replace my separate WordPress page speed plugin and CDN plugin?
In most cases yes. Page caching, minification, GZIP, lazy loading, font optimization, browser caching, object caching, WordPress CDN support and database cleanup are all in one plugin, so you are not stacking a WordPress page speed plugin on top of a cache plugin on top of a database tool.
Will it help my Core Web Vitals?
It targets the parts a plugin can influence. The static cache improves server response time, the LCP preload picks the largest image on the page rather than the first, lazy loading defers offscreen media, and the automatic Cumulative Layout Shift fix stops the layout jumping. Page weight and DOM size are reported to you, since only a person can fix those.
What is the MCP server for?
The MCP server lets an AI assistant connect to your site and use the same tools the dashboard uses, such as purging cache, checking preloader status, running a score and reading or updating settings. Read-only connections stay read-only, and credentials cannot be written unless you explicitly grant that permission when connecting.
Will this break my site?
Very unlikely. xSpeed Cache includes safety checks for every optimization: minification falls back to the original if anything looks off, and the cache bypasses logged-in users, admin pages, AJAX and REST requests automatically. If something ever looks wrong, you can toggle any feature off individually.
How do I clear the cache?
Click Purge in the xSpeed Cache dashboard, or use Purge xSpeed Cache in your admin bar. The cache also clears itself automatically whenever you publish or update content.
Can I use xSpeed Cache alongside Cloudflare?
Yes. The built-in Cloudflare module connects your zone and auto-purges Cloudflare's cache whenever xSpeed Cache purges its own, so both caches stay in sync.
Can I disable minification temporarily for debugging?
Yes. Either toggle the option off in the admin UI, enable WP_DEBUG (xSpeed Cache automatically skips HTML minification when debug is on), or use the xspeed_skip_minify filter.
Does xSpeed Cache send my data anywhere?
By default, no. The only request is a check to your own site's home URL to confirm GZIP is active. Everything else, including usage analytics, speed tests, xSpeed Scan, Cloudflare and click-to-play video posters, runs only after you turn it on or press a button. Each service is listed in the External services section.
更新日志:
- Fixed: A page purged at the moment the PHP serve path sends it from cache no longer goes out as a cached hit with an empty body.
- Fixed: On nginx, requests over HTTP/3, or with an upper-case host or
:443in the host, now get the cached file instead of going to PHP. Copy the updated nginx snippet to apply it. -
Fixed: The preloader tries a slow page once more before counting it as failed, and its report counts warmed, failed and not-cached pages separately. The page-warm timeout can be changed with
xspeed_preloader_request_timeout. Object Cache: -
Improved: Flushing a Redis object cache takes the same time at any size: Purge All went from about 340 ms to 25 ms with 155,000 keys. Old values are deleted in the background, and
wp xspeed objcache statusreports how that went. - Improved: Multi-key object-cache calls use batched reads and Redis write pipelines.
- Fixed: Automatic page purges keep the object cache warm. Explicit purges and plugin activation or deactivation still flush it.
- Fixed: Fetching or refreshing third-party files no longer flushes the object cache.
- Fixed: A flush that Redis refuses or that fails now shows as an error. Optimization:
- Improved: When Load CSS without blocking leaves a page alone, it says why.
- Fixed: Defer JS and Delay JS leave the login page alone, so login captchas such as Cloudflare Turnstile load and the login goes through. This includes custom login URLs.
- Fixed: xSpeed no longer optimizes the Bricks builder or its previews, so elements no longer disappear in the editor.
- Fixed: A long unquoted attribute, such as a base64 image, no longer blanks the page.
- Fixed: A document-relative image is no longer preloaded from a broken address, and an image the theme already preloads is no longer preloaded twice. AI / MCP:
- Improved: An add-on can report when its licence expires, and when and where its licence was last checked.
- Fixed: An owner's approval for a database clean covers only the categories the owner was shown, and an MCP token cleans only the categories it covers.
- New: Cache pages for shoppers with a cart keeps one cached copy per cart, so a shopper with items in the cart no longer skips the page cache. It is off by default and shows only while WooCommerce is active. Cart, checkout and account pages, add-to-cart requests and logged-in users are still not cached, and a product, price or stock change clears every cart copy.
- New: An add-on can hold the cache write for up to 5 minutes while a page's optimized version is about to land, so the unoptimized page is not cached first (
xspeed_cache_write_hold). - Fixed: A browser that reloads a cached page with a conditional request now gets a real 304 on the PHP serve path. Before, it got a 200 with an empty body, which showed a blank page and could be stored by a CDN.
- Fixed: Requests from the Hub renderer and Speed Scan no longer count as visits in WP Statistics, Slimstat or the hit ratio when they send a browser user agent. Optimization:
-
New: Main (LCP) image. In the block editor sidebar or the classic editor, choose which image a page preloads: automatic, the featured image, an image you pick, or none. Resource Hints has site-wide rules by page type or path. The chosen image gets
fetchpriority="high"and is not lazy-loaded. - Fixed: With Delay JS on, Slider Revolution no longer shows its "jquery.js library include" error in place of the slider, the hero keeps its height until the delayed scripts run, and the Bridge theme's logo shows. This also holds on pages the cache does not store, such as for logged-in users. Dashboard & Admin UX:
- Fixed: A link to a module that lives in another page's tab opens that tab.
- New: Third-party files copies CSS and JavaScript from hosts you allow onto your site and points the page at the copy, so Combine CSS, Delay JavaScript and the CDN can work on them. It is off by default. Once it is on, it copies from nine common library hosts, such as cdnjs and jsDelivr, and you can edit that list.
- New: Local Analytics serves the Google Analytics script from your site, so PageSpeed no longer flags its short cache lifetime. It is off by default, and turning it off puts Google's address back.
- Fixed: With Lazy-load your own videos on, audio players with no preload setting no longer download their file on page load. A preload you set yourself, and autoplay players, are left alone. Dashboard & Admin UX:
- Fixed: An add-on's settings on an unlicensed site now show the licence card, instead of switches that Pro refuses to save. Older releases are listed in changelog.txt, included with the plugin, and at xspeedcache.com/changelog.
