You can now connect FastPixel to your Redis or Memcached server and let our plugin handle the rest. Object caching stores the results of database queries in memory, so WordPress skips repetitive work on every page load, meaning faster pages and less load on your server. No configuration needed. Just connect and go. – No need for additional plugins – Tuned for WooCommerce compatibility – Built for maximum performance with the same resources – Smart cache prefetching – Fully compliant with WordPress – Improved efficiency with simple settings and defaults – Encrypted communication 💡 Why choose FastPixel Caching plugin? Website Performance Boost: Just activate the plugin and within seconds the optimized webpages will start to be served. Lower the CPU/RAM Impact: Using the plugin will reduce the impact on the resources used by your website. All the CPU intensive processing is done in the cloud and resulting pages will generally be served from a cached version and the optimized images from the CDN. Automated Core Web Vitals Optimization: FastPixel takes care of all technical aspects automatically. Smart Cache Warmup/Update: The cache warmup and update are taken care of automatically in a smart way. Pages are cached as they are visited and also updated if you update the content. Critical CSS: CCSS is automatically generated for each page for lightning-fast page loads. CSS/JS Processing: CSS/JS files are combined and also minified and compressed before they are served from our CDN. HTML Optimization: A single, highly optimized HTML file is generated, adaptively serving the ideal webpage based on the visitor’s viewport or device (e.g., mobile, tablet, laptop). DNS Preconnects: Accelerates resource fetching, reduces the access time to external resources. Font Processing: All the techniques to accelerate the processing and delivery of fonts are employed, e.g. font subsetting, font loading control, font compression, font embedding (lower CLS result). Image Resizing & Optimization: Images are automatically resized to fit their placeholders, optimized, and delivered through the ShortPixel CDN. Automatic Next-Gen Images Delivery: Based on the visitor’s browser capabilities, original JPG, PNG, or GIF images are converted to and served as WebP or AVIF when supported. For browsers without support, the original format is provided. 🌟 Happy users that use our plugin If you’re satisfied with the test, just search for “FastPixel” in your WordPress Dashboard > Plugins, install the plugin and see for yourself how much faster your site becomes.

This is useful when integrating FastPixel with custom plugins, WooCommerce, ACF, or any workflow that modifies content outside the standard WordPress editor. Example hooks: do_action(‘fastpixel/purge/all’); – Purges the entire site cache. do_action(‘fastpixel/purge/single’, [‘id’ => 123]); – Purges the cache for a single post, page, or taxonomy term. do_action(‘fastpixel/purge/url’, ‘https://example.com/my-landing-page/’); – Purges the cache for a specific URL. For a detailed documentation about the hooks, please see this page: https://fastpixel.io/docs/fastpixel-hooks/

DietPress is a free WordPress speed optimization plugin with a built-in page cache. Page caching, browser caching, GZIP and Brotli compression, deferred JavaScript, critical CSS, image loading attributes, preloading, locally hosted Google Fonts and selective asset loading, all in one plugin and all free. And it goes further than a caching plugin: it also puts WordPress itself on a diet, switching off the features your site never uses. It pairs that with a clean, risk-based interface. Everything is configurable, the optimizations are already on by default, and nothing is hidden behind a paid tier. Activate it and your site is faster, or open the settings and tune every detail. By default WordPress loads functions, services and scripts that most sites do not need. They slow down loading times and consume hosting resources. DietPress lets you trim that fat and apply battle-tested performance tweaks, with a clear description of what each option does and what might break, organized by risk level so you always know what is safe. WHY CHOOSE DIETPRESS Page caching, for free. Serve anonymous visitors a copy stored on disk instead of building the page again. The feature people buy WP Rocket or a NitroPack subscription for, with no licence and no monthly fee. No drop-in, no changes to wp-config.php. Unlike WP Super Cache or W3 Total Cache, DietPress installs no advanced-cache.php and never edits wp-config.php. Switching it off leaves your site exactly as it was, with nothing orphaned behind. It tells you why. Most cache plugins leave you guessing when nothing is cached. DietPress reports its own status, tests itself against your home page, and names the exact reason a page was skipped. WooCommerce-safe by design. Carts, checkout, my account and any visitor carrying a cart cookie always get the live site, so nobody ever sees somebody else’s basket. Diet as well as speed. Where Perfmatters focuses on disabling scripts, DietPress covers that ground and adds page caching, critical CSS, local Google Fonts and a dashboard, admin and email cleanup, in one plugin. Light on your server. No account, no external service, no telemetry, no upsell nags. Everything runs on your own hosting. WHAT THE PAGE CACHE DOES TO YOUR RESPONSE TIME Measured on a WordPress 7.0 install with GeneratePress, WooCommerce and a 76 product catalogue, PHP 8.5, taking the median of 15 requests per URL. Your own hosting will give different figures, but the shape of the result will not change. Server response time, the same pages with the page cache off and on: Home page – 52.7 ms without, 15.1 ms with, 71% faster WooCommerce shop – 45.4 ms without, 14.8 ms with, 67% faster A 110 KB article – 43.0 ms without, 15.1 ms with, 65% faster A 98 KB page – 41.0 ms without, 14.9 ms with, 64% faster A product category – 41.3 ms without, 15.1 ms with, 63% faster The interesting part is not the percentage, it is that the cached figure barely moves. Serving a stored file costs the same whether the page was cheap or expensive to build, so the saving grows with the size of your site rather than with the power of your server. The heaviest page in the test is the one that gained most. It also changes how much traffic your hosting can take at once. In the same test the server went from serving about 40 visits a second to more than 210, five times as many, on exactly the same plan. That is what keeps a small site standing up when one of your posts does well. TWO THINGS IN ONE PLUGIN 1. Performance optimizations (on by default) Automatic Critical CSS inlined in the head (optional experimental deferral of non-critical CSS) JavaScript defer parsing with smart dependency handling Image loading attributes safety net: lazy loading, decoding=async and fetchpriority for images that bypass core Automatic image dimensions for better CLS scores (including picture elements) Resource hints: preconnect and DNS prefetch for common third-party origins Theme stylesheet, critical fonts and logo preloading for a faster LCP Google Fonts display=swap Google Fonts local hosting: serve the fonts your theme uses from your own server, GDPR-friendly with a silent fallback to the Google CDN (opt-in) Selective third-party loading: WooCommerce, Contact Form 7, block library, Slider Revolution, TablePress, Smash Balloon, Formidable Forms and Everest Forms assets only load where they are used (opt-in) RSS feed optimization (cache headers and item limit) Server rules in .htaccess: browser caching with a configurable lifetime for media, for styles and scripts and for fonts, GZIP and Brotli compression, immutable cache headers, CORS for fonts and keep-alive (master switch plus per-feature toggles) Database maintenance: daily expired-transient cleanup and safe query optimizations Page cache: store each page on disk and serve it to anonymous visitors without building it again, with automatic purging, gzip precompression and a status panel that says whether it is working (opt-in, in its own tab) 2. Put WordPress on a diet (risk-based, opt-in) Light (safe for any site): emojis, RSD/WLW tags, shortlinks, self-pingbacks, comment pagination, and more Moderate (evaluate first): oEmbed, jQuery Migrate, Dashicons on the frontend, Global Styles and Duotone, remote block patterns, avatars and Gravatar, comment threading, and more Strict (site-specific): granular RSS feed control, Heartbeat API mode, post revisions and autosave, disable comments, XML sitemap, native lazy loading/fetchpriority, content types, selective loading for WooCommerce, Contact Form 7, block assets, Slider Revolution, TablePress, Smash Balloon, Formidable Forms and Everest Forms, and more Widgets: dashboard widgets (including third-party ones from Yoast, WooCommerce, Elementor, Jetpack, Wordfence, Rank Math, Gravity Forms), classic sidebar widgets, block-editor widgets and the Customizer Emails: silence the automatic emails WordPress sends on its own, grouped by area: auto-update results for core, plugins and themes (plus the new-version notice), comment moderation and new-comment notices, and new user, password and email-change notices, plus toggles for the admin email verification prompt and post-by-email. Every option is off by default, and critical notices such as a failed core update are always kept SCALE, PROFILES AND ANALYZER Savings indicator: HTTP requests removed, CSS/JS saved and active optimizations at a glance Quick profiles: Personal Blog, WooCommerce Store, Landing Page and Maximum Cleanup Site analyzer: personalized recommendations based on your active plugins and content, page cache included Import and export your whole configuration as a JSON file COMPATIBILITY AND EXTENSIBILITY The plugin includes filters for developers: dietpress_critical_css – Customize the inline critical CSS dietpress_critical_css_handles – Define which CSS handles are critical dietpress_skip_defer_script_handles – Opt scripts out of the JavaScript defer dietpress_skip_defer_style_handles – Opt stylesheets out of the CSS deferral dietpress_preconnect_hints – Customize preconnect origins dietpress_dns_prefetch_domains – Customize DNS prefetch domains dietpress_critical_fonts – Define critical fonts to preload dietpress_exclude_local_fonts – Exclude Google Fonts stylesheets from local hosting dietpress_selective_{module}_has_content – Mark a page as showing the content of a selective loading module, so its assets are kept. The module is wc, cf7, formidable, everest_forms or revslider dietpress_selective_{module}_styles / dietpress_selective_{module}_scripts – Adjust the handles removed by each module dietpress_selective_page_hides_content – Mark a page as rendering content the content scan cannot reach, so no module removes anything (this is what handles Elementor) dietpress_selective_is_wc_page – Override the WooCommerce page detection of selective loading dietpress_selective_wc_keep_cart_fragments – Keep the cart fragments script when your theme has a hand-coded mini-cart dietpress_selective_cf7_has_form – Mark pages that load a Contact Form 7 form dynamically dietpress_selective_blocks_dequeue – Override the block library dequeue decision dietpress_selective_everest_forms_dequeue_dashicons – Keep Dashicons when another plugin enqueues it directly dietpress_native_sitemap_in_use – Tell DietPress your plugin builds on the native WordPress sitemap, so the option that removes it becomes unavailable dietpress_cache_bypass – Keep the current page out of the page cache dietpress_cache_bypass_cookies – Adjust the cookie name prefixes that make a visitor uncacheable dietpress_cache_ignored_params – Adjust the query parameters that do not change the page dietpress_cache_exclude_urls – Adjust the excluded URL patterns dietpress_cache_post_urls – Adjust the URLs purged along with a post Compatible with: Well-coded themes and page builders (Divi, Elementor, Beaver Builder, Bricks Gutenberg) Cache plugins (WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache, etc.). The one exception is the optional page cache module, which will not run beside another page cache and says so; everything else in DietPress works alongside them as it always has Security plugins (DietPress focuses on performance and deliberately leaves security to them; we recommend our free Vigilant) CDNs (Cloudflare, StackPath, KeyCDN, etc.) thanks to CORS and Vary headers WordPress Multisite (except the optional page cache module, which does not support it yet) HOW TO VERIFY THE OPTIMIZATIONS Cache rules: check your .htaccess for a block marked # BEGIN DietPress with immutable Cache-Control headers Logo preload: view page source and look for pointing to your logo Critical CSS: view source and look for in the head Compression: test at giftofspeed.com/gzip-test Always measure with tools like Google PageSpeed, GTMetrix or WebPageTest, and run each test at least twice to account for caching.
