The Off Switch (formerly WP Avoid Slow) vs WP Fastest Cache – WordPress Cache Plugin

WordPress prioritises backwards compatibility. That’s a feature. It also means every install ships with things you didn’t ask for. An emoji CDN script. An oEmbed script. A Windows Live Writer manifest (discontinued 2017). Dashicons loaded for logged-out visitors. Heartbeat polling every 15 seconds. A version tag that tells the world exactly which WordPress you’re running. None of these are bugs. They’re just not needed on most sites. Disable what you don’t need. Keep what you do. The Off Switch lets you disable each one, individually. One screen, every switch A live counter shows how many switches are on. A sticky bar keeps Save, the filter, and state chips (All / On / Off / Changed / New) in reach while you scroll. Changed switches are highlighted until you save, and an “unsaved changes” pill shows exactly what you’ve flipped before you commit. Jump between sections with live per-section counts, or copy a WP-CLI command that replicates your whole configuration on another site. Every switch card states what it removes, what it saves, and what to watch out for. All 104 switches were functionally verified against a live WordPress 7.0 install for this release. Bloat Remover Emoji script – ~15 KB + 1 HTTP request. Browsers handle emoji natively. Embed script – ~4 KB + oEmbed discovery links in . RSD link – Really Simple Discovery. Only needed for legacy XML-RPC clients. WLW manifest – Windows Live Writer has been discontinued since 2017. WordPress 6.3 removed this link from core — the switch matters on WordPress 6.2 and older. WP version tag – Stops advertising your WordPress version to the world. Shortlink – Removes from and HTTP headers. Search engines ignore it. Asset query strings – Strips ?ver= from scripts, styles, and WP 6.5+ Script Modules so CDNs and proxies cache correctly. XML-RPC – Closes a common brute-force attack vector. XML-RPC Kill Requests – Goes further than disabling: hard-kills any incoming xmlrpc.php request with a 403 before WordPress loads at all. Heartbeat API – Reduces admin polling from every 15 s to every 60 s. Dashicons (frontend) – ~35 KB (CSS + font) saved for every logged-out visitor. REST API Discovery Link – Removes from . Safe to remove on standard sites. RSS Feed Links – Removes feed autodiscovery tags from . Modern browsers no longer act on them. Leave enabled if you publish an RSS feed. Speculation Rules (WP 6.8+) – Disables the WP 6.8+ Speculation Rules API that prefetches links before users click. Can inflate analytics, increase server bandwidth, and trigger consent flows on unfetched pages. Disable All Feeds – Redirects all RSS and Atom feed URLs to the homepage. For sites with no RSS subscribers. Comment Auto-Links – Stops WordPress from converting plain-text URLs in comments into clickable links. Editor Autosave – Deregisters the autosave script that POSTs editor content to the server every 60 seconds. For teams that prefer explicit saves. DNS Prefetch – Removes all hints from . Redundant when Emojis and Embeds are already disabled. Recent Comments Inline CSS – WordPress outputs a small inline block in whenever the Recent Comments widget is active. Remove it if your theme already styles the widget. Script & Style Control jQuery Migrate – ~30 KB. Modern themes don’t need it. Block Library CSS – ~7 KB loaded on every page, even with no Gutenberg blocks. Global Styles (theme.json CSS) – 10-50 KB inline CSS from block themes. SVG Duotone Filters – Hidden SVG blob injected on every page, even with no duotone images. WordPress 6.3 made duotone output on-demand — the switch matters on WordPress 6.2 and older. Script/Style type attributes – type="text/javascript" and type="text/css" are redundant in HTML5. Defer non-critical JavaScript – Adds defer so scripts don’t block HTML parsing. jQuery is never deferred. Move scripts to footer – Relocates enqueued scripts from to just before . jQuery is never moved. Template Output Buffering (WP 7.0) – Since WordPress 7.0, classic themes get every frontend page buffered in memory in full and re-parsed before a single byte reaches the visitor, so late-printed block styles can be hoisted into . Turning the buffer off restores streamed output for faster TTFB and lower peak memory. Block themes are unaffected. WordPress Behaviour Tweaks Self-pingbacks – WordPress pings your own posts when you link between them – a wasted HTTP request that creates an unwanted comment on the target post. Capital P filter – WordPress corrects “WordPress” to “WordPress” on every rendered string. Remove if you don’t need the autocorrect. Limit post revisions – WordPress stores unlimited revisions per post. Caps revisions at 3 to prevent silent database growth on active editorial sites. Attachment pages – WordPress creates a full template page for every uploaded file. These waste crawl budget on most sites. Sends a 301 redirect to the parent post instead. Comments – Closes all comments and pingbacks site-wide, hides existing comments on the frontend, and removes comment-related UI from wp-admin (Comments menu, admin bar node, dashboard widget). Enable only if your site does not use comments. Search – Redirects all WordPress search queries (/?s=) to the homepage with a 301, preventing bots from triggering repeated database queries. Also removes search forms rendered via get_search_form(). Hardcoded forms in theme templates are not affected. oEmbed Provider – WordPress registers a REST endpoint at /wp-json/oembed/1.0/embed so other sites can embed your content via the oEmbed protocol. Remove it if you don’t want your content embeddable externally. Does not affect your ability to embed others’ content. Post via Email – Removes the Post via Email configuration from Writing Settings and disables the feature. Almost no modern site uses email-to-post. Update Services (Ping-o-Matic) – Removes Update Services from Writing Settings and stops outbound pings to weblog ping services on every published post. Native XML Sitemap (WP 5.5+) – Disables WordPress’s built-in XML sitemap generator. Most sites use external SEO plugins (Yoast, Rank Math) for sitemaps instead. Removes unnecessary redirects and reduces crawl overhead (default OFF). oEmbed Auto-Embed – Disables WordPress from regex-scanning post content for [embed] shortcodes and oEmbed patterns on every frontend page load. For sites that do not embed external content, removing this filter saves processing overhead (default OFF). Database & Query Expired Transients – Schedules a daily cleanup of expired transient rows in wp_options. Useful on low-traffic sites where WP-Cron can go days without firing. Abandoned Auto-Drafts – WordPress creates an auto-draft every time the post editor opens. Abandoned sessions leave these rows permanently. Runs a daily sweep to delete auto-drafts older than 30 days. Skip Row Count on Singles – On every single post or page, MySQL runs SQL_CALC_FOUND_ROWS to count total matching rows – a full index scan only needed for paginated archives. Removes that sub-query on all singular views. Adjacent Post Links – Older WordPress queries the previous and next post on every single post page to output in — two extra DB queries per page load. Google dropped support for these hints in 2019, and modern WordPress no longer outputs them; the switch matters on older installs. Reduce Trash Retention – WordPress keeps trashed items for 30 days before permanent deletion. A daily sweep permanently deletes posts and comments trashed more than 7 days ago, keeping wp_posts leaner on active editorial sites without affecting normal recovery workflows. Image Performance Google Fonts display:swap – Without font-display:swap, the browser hides text while your Google Font downloads (FOIT). Adds display=swap to every Google Fonts URL so visitors see text immediately. Add missing image dimensions – Images without width and height attributes cause layout shifts (CLS). Reads dimensions from attachment metadata and injects them automatically. LCP image priority – Adds fetchpriority="high" to the first content image so the browser loads it before lower-priority resources. Adds fetchpriority="low" and decoding="async" to all others. Lazy load images – Adds loading="lazy" to images below the fold. The first image is never lazy-loaded – it is the LCP candidate and must load immediately. Disable PDF thumbnails – WordPress generates thumbnail previews for every uploaded PDF when ImageMagick is available. Rarely used on the frontend; adds significant upload processing time. Disable scaled images – WordPress 5.3+ creates a downsized -scaled copy of any image whose longest side exceeds 2560 px on upload. On most sites this extra file is never served. Disabling it stores the original as-uploaded. Applies to new uploads only. Disable extra image sizes – WordPress 5.3 added 1536×1536 and 2048×2048 intermediate sizes to every image upload. These oversized copies are rarely requested and waste disk space. Theme and plugin image sizes are not affected. Applies to new uploads only. Security & Admin Hardening Block User Enumeration – WordPress redirects ?author=1 to /author/username/, exposing registered usernames. Intercepts those requests and redirects to the homepage before the username is revealed. Disable Author Archives – Redirects all /author/username/ pages to the homepage. For sites with no author profile pages. Disable File Editor – Defines DISALLOW_FILE_EDIT to remove the plugin and theme code editor from wp-admin. Eliminates a code-injection surface a compromised admin account could exploit. Disable Application Passwords – Removes the Application Passwords UI and stops all tokens from being accepted. For sites that don’t use REST API or XML-RPC integrations. Suppress Admin Email Check – Disables the periodic full-screen prompt asking admins to confirm their email address. One less interruption, no functional change. Remove X-Pingback Header – Strips X-Pingback: from every HTTP response, stopping the site from advertising its XML-RPC endpoint URL to scanners. Clean Admin Bar – Removes the WordPress logo dropdown, the duplicate “Visit Site” link, and the admin bar search for a less cluttered editing environment. Hide Update Nag for Non-Admins – Hides the core update notice from editors and contributors who cannot action it. Administrators still see it normally. Restrict REST API to Logged-In Users – The REST API is publicly accessible by default, allowing unauthenticated enumeration of posts, users, and other data. Restricting access to authenticated users reduces the attack surface. Will break public REST consumers such as headless frontends. Redirect Unauthenticated Admin Access – By default, visiting /wp-admin/ without being logged in redirects to the login page, confirming a WordPress admin area exists. This redirects unauthenticated requests to the homepage instead, reducing information disclosure to scanners. AJAX, Cron, WP-CLI, and admin-post.php requests are never affected. Hide Author Sitemap – WordPress 5.5 added a built-in XML sitemap that includes a users file listing the author archive URL for every user with published posts — up to 2,000 usernames, publicly accessible. Removes the users entry from the sitemap index entirely (WP 5.5+, default ON). Remove X-Redirect-By Header – WordPress 5.1+ adds an X-Redirect-By: WordPress header on every redirect, openly advertising that the site runs WordPress. Removes it from all redirects (default ON). Hide PHP Version Header – PHP sends an X-Powered-By: PHP/x.x.x header on every response, exposing your exact PHP version to every visitor and scanner. Removes it from all responses (default ON). Generic PHP Error Messages – WordPress fatal error messages can include internal file paths and line numbers. Replaces them with a generic response that reveals nothing about server structure (default ON). Hide Admin Bar on Frontend – Removes the WordPress admin toolbar from the public-facing site for all logged-in users. Reduces frontend CSS/JS overhead for logged-in sessions (default OFF). Remove Dashboard Welcome Panel – Removes the “Welcome to WordPress” panel from the dashboard home screen for all users (default OFF). Remove Default Dashboard Widgets – Removes four default dashboard widgets including WordPress Events and News, which makes an outbound HTTP request to api.wordpress.org on every dashboard load (default OFF). Remove Admin Footer Text – Removes the “Thank you for creating with WordPress” text and WordPress version number from the wp-admin footer (default OFF). Disable REST Users Endpoint – WordPress’s REST API exposes /wp-json/wp/v2/users publicly, returning usernames and slugs for all users with published posts. Removes this endpoint for unauthenticated requests only — Gutenberg and plugins that need it while logged in are unaffected (default ON). Disable Email Change Notifications – WordPress sends emails to users when their email address or password changes. On agency-managed sites these are noise. Suppresses both notification types (default OFF). Disable Auto-Update Emails – WordPress emails after every automatic core, plugin (WP 5.5+), and theme (WP 5.5+) update. On sites where auto-updates are routine these arrive constantly (default OFF). Auto-Update Emails: Errors Only – A middle ground: suppresses core auto-update success emails only. Failure emails still arrive so you know when action is needed (default OFF). Skip Bundled Themes on Upgrade – Defines CORE_UPGRADE_SKIP_NEW_BUNDLED to stop WordPress installing a new default theme on every core upgrade. Existing themes are not affected (default OFF). Disable Site Health – Disables WordPress Site Health checks entirely. Site Health runs a 12-hour background cron job and makes REST API calls on every admin page load, fetching a list of ~20 WordPress.org API endpoints. On managed hosting with automated updates, these checks are redundant and add unnecessary server load (default OFF). WordPress 7.0 Off switches for the new subsystems WordPress 7.0 turns on by default. AI Support – WordPress 7.0 ships a built-in AI client framework that initialises on every request. Filters wp_supports_ai to false so the AI subsystem never bootstraps — no providers, no AI REST surface, no AI options on the Connectors page. Connectors Registry – WordPress 7.0 initialises a connector registry on every request, frontend included, registering the bundled Akismet connector and any AI providers. Skips registry initialisation entirely on sites that use no connectors. Core AI Abilities – Stops WordPress from registering its built-in AI abilities (site info, user info, and more) when the Abilities API registry is first used. Completes the AI off switch. Abilities REST API – Removes the wp-abilities/v1 REST namespace (list, categories, and run endpoints) that exposes server-side abilities to REST clients. Icons REST Endpoint – Removes the /wp/v2/icons endpoints that serve SVG icon data to the block editor icon picker. AI Connectors Page – Removes the Connectors submenu from Settings, hiding the AI provider configuration page. Admin View Transitions – Removes the CSS View Transitions stylesheet WordPress 7.0 enqueues on every wp-admin screen, restoring instant admin navigation. Command Palette – Removes the ⌘K / Ctrl+K command palette: the admin bar trigger button and the JS bundle enqueued on every wp-admin page. Block Editor Remote Block Patterns – WordPress fetches patterns from api.wordpress.org on every editor load. …

Page Caching – Page caching feature generates and store static HTML files from your dynamic WordPress blog to reduce initial server response time, and improving page load time. Page cache and caching play a critical role in improving website speed and overall web performance. By storing frequently accessed data, effective caching reduces server workload and significantly improves cache performance, allowing pages to be delivered faster to users. This optimization directly lowers load time and enhances page speed, resulting in a smoother user experience and better SEO. Minify Html – Using an HTML minifier is an effective way to reduce HTML size and optimize HTML by removing unnecessary spaces, comments, and line breaks. A smaller HTML file helps reduce page size, which directly improves page speed and leads to a faster website experience for users. By focusing on web performance optimization, optimized HTML allows browsers to load and render pages more efficiently, helping to improve website speed, lower bandwidth usage, and deliver better overall performance across all devices Minify Css – CSS minify techniques play a crucial role in modern web development by reducing unnecessary characters through a reliable css minifier. With effective css compression, developers can compress CSS files and apply proper css minification to optimize CSS for production environments. This approach helps reduce CSS file size, which directly contributes to improve website speed and overall css performance optimization. As part of a broader page speed optimization strategy, these practices significantly enhance website performance optimization and lead to better website loading performance, especially on mobile and low-bandwidth connections Enable Gzip Compression – Reduce the size of files sent from your server to increase the speed to which they are transferred to the browser Leverage browser caching – Browser cache plays a critical role in how efficiently a web browser cache stores static resources like images, stylesheets, and scripts, directly impacting page load speed. By allowing returning visitors to load files from their local browser cache instead of downloading them again, websites can significantly reduce server requests and improve website speed. Properly configured browser caching not only creates a faster and smoother user experience but also helps lower bandwidth usage and enhance overall site performance Combine CSS – Reduce number of HTTP round-trips by combining multiple CSS resources into one Combine JS – Combining JavaScript files is a core technique in javascript optimization and js optimization, especially when the goal is to reduce requests and improve page load speed. By combine js assets or combine javascript files into a single bundle, developers can streamline how scripts are delivered to the browser. Whether you call it js combine or javascript combine, the idea is the same: fewer HTTP requests mean faster performance. Similarly, approaches that merge js or merge javascript—also known as js merge or javascript merge—help eliminate overhead caused by loading multiple separate files. When done correctly, combining and merging scripts leads to cleaner delivery, better caching, and noticeably faster websites Disable Emoji – You can remove the emoji inline css and wp-emoji-release.min.js Premium Performance Optimization The free version is enough to speed up your site but in the premium version there are extra features such as Mobile Cache, Widget Cache, Minify HTML Plus, Minify CSS Plus, Minify JS, Combine JS Plus, Defer Javascript, Optimize Images, Convert WebP, Database Cleanup, Google Fonts Async, Lazy Load and Delay JS for super fast load times. Mobile Cache Widget Cache Minify HTML Plus Minify CSS Plus Minify Javascript – Minify JS is a core step in web performance optimization because js minify techniques remove unnecessary characters, comments, and whitespace, making files smaller and faster to load. Through proper javascript minification, developers can compress JavaScript assets and significantly reduce transfer size, which directly supports effective js optimization and overall javascript optimization strategies. When combined with caching and code splitting, minified scripts help improve website speed, lower bandwidth usage, and enhance user experience. As a result, page speed optimization becomes easier to achieve, leading to faster render times and better search engine rankings. Combine JS Plus Defer Javascript – Eliminate render-blocking JavaScript resources. Consider delivering critical JS inline and deferring all non-critical JS Optimize Images – Optimized images load faster and consume less cellular data. Looking for an easy image compressor?
