Fastcache by Host.it vs WP-Optimize – Cache, Compress images, Minify & Clean database to boost page speed & performance

FastCache è l’evoluzione del plugin FastCache 1.0.x sviluppato da HOST S.p.A. (Host.it). La versione attuale introduce un sistema completo di caching e ottimizzazione per WordPress, progettato per migliorare le prestazioni del sito e ridurre in modo significativo il carico sull’infrastruttura. Il plugin non si limita più alla sola integrazione CDN, ma include tutte le funzionalità tipiche di un moderno plugin di caching, integrandole in un unico strato software coerente e modulare. Full Page Caching FastCache implementa un sistema di full page caching nativo, basato sulla generazione di versioni HTML statiche delle pagine. Le pagine cache vengono servite direttamente dal web server tramite reindirizzamento a livello di .htaccess, evitando completamente: l’esecuzione di PHP, le query al database, il caricamento dello stack WordPress. Questo approccio consente di ridurre drasticamente il consumo di CPU e RAM, liberando risorse di sistema per le operazioni che richiedono elaborazione dinamica, come: carrello e checkout, gestione degli ordini, moduli di invio dati, ricerche, processi applicativi critici. Il risultato è una maggiore stabilità del sito e una migliore gestione dei picchi di traffico. CDN e gestione della cache FastCache integra una CDN proprietaria gestita da HOST S.p.A. La comunicazione con la CDN avviene tramite un token di autenticazione univoco per ciascun sito, che consente: gestione dinamica dei TTL, purge selettivo dei contenuti, sincronizzazione automatica tra cache locale e cache CDN. Quando un contenuto viene modificato, FastCache invalida automaticamente: – la pagina aggiornata, – la homepage, – le categorie correlate, – archivi, feed RSS e sitemap associati. Questo meccanismo consente di mantenere TTL ridotti garantendo contenuti sempre aggiornati senza interventi manuali. Ottimizzazione delle risorse Il plugin include strumenti avanzati per: combinazione e minificazione di CSS e JavaScript, minificazione HTML, lazy load di immagini, iframe ed elementi HTML, ottimizzazione dinamica delle immagini con conversione WebP e AVIF, gestione automatica di srcset, preload delle risorse tramite HTTP/2. Le funzionalità sono configurabili e adattabili sia a siti semplici sia a installazioni complesse, inclusi e-commerce basati su WooCommerce. Analisi e diagnostica FastCache integra: – test di performance basati su Google PageSpeed Insights e Lighthouse, – strumenti di diagnostica dell’ambiente di hosting, – rilevamento di conflitti con altri plugin di caching o ottimizzazione. Queste funzioni permettono di verificare la correttezza della configurazione e la compatibilità dell’ambiente. Prodotto italiano FastCache è un prodotto 100% italiano: – sviluppo del plugin in Italia, – servizi CDN basati su server italiani, – infrastruttura gestita ed erogata interamente in Italia, – documentazione e supporto tecnico in lingua italiana. Documentazione ufficiale: https://assistenza.host.it/area-tecnica/fastcache/pluginwordpress Compatibilità FastCache è progettato per operare come unico plugin di caching. È fortemente consigliato disattivare altri plugin di caching per evitare sovrapposizioni o conflitti. Il plugin include inoltre impostazioni dedicate per WooCommerce, che consentono di mantenere cacheabili le pagine compatibili senza compromettere il corretto funzionamento del carrello e delle sessioni utente.

MORE THAN A CACHING PLUGIN WP-Optimize is trusted by more than 1 million WordPress website owners to boost performance and reduce page load times to improve your site’s user experiences and SERP rankings in Google. It does this in four clever ways: 1. It caches your site Caching is the process of storing a temporary HTML version of your site on the server so it can be retrieved more quickly for the user. It’s a sure-fire way to ensure web pages load at lightning-fast speed. Turn it on in just one click. 2. It compresses images Large images can really impact page speed load times. WP-Optimize makes it easy to identify and compress images to your preferred lossy / lossless settings in a couple of clicks. 3. It cleans the database Your WordPress database stores everything that you need, plus some things that you don’t. WP-Optimize cleans and optimizes the database to speed up your site and save server resources. 4. It minifies On top of its three main features, WP-Optimize Cache also has the more advanced minification feature. Together with caching, minification dramatically improves performance and page speed load time. 1. CACHE YOUR SITE Turn on caching in just one click: WP-Optimize automatically and optimally configures itself for your WordPress site. Turn it on in one-click or refine its settings if you prefer. More cache features: Cache preloading: This feature emulates a visit to your site, meaning cached files are served straight away, speeding up your site from the very first visit. GZIP Compression: When the server isn’t configured to do so, WP-Optimize delivers HTML, CSS and JS files to the user’s browser as smaller, compressed files, reducing the size of pages and style sheets by up to 90%! Preload key requests: Recommended by Google to improve page speed times. Critical resources (things like font files) get loaded first, so the page loads much faster [Premium]. Use cache settings to: Serve cached content to logged in users: Turn this on if content stays the same for logged in users (or turn on and exclude URLs where content does change e.g. my account areas). Exclude content from cache: Exclude by URL, conditional tags, browser agent strings or list cookies that should prevent caching when set (advanced user settings). Deliver device-specific cache: Serve separate cache files to desktop and mobile devices . This ensures that responsive features e.g. desktop and mobile menus are cached separately and served correctly. User per role cache: Useful if your website delivers different content to different user roles. e.g. an e-commerce site that displays different content to resellers or consumers [Premium]. User specific cache: Serves separate cache files to individual users. Useful for websites with personalised content e.g. Learning management systems [Premium]. Cache purging permissions: Select which user roles are allowed to purge the cache e.g. admin only or perhaps a ‘teacher’ role in an LMS setting only [Premium]. 2. COMPRESS IMAGES Lossy or lossless compression options: Choose between maximum space saving, best image quality or somewhere in-between. WebP conversion: Recommended by Google, WebP can achieve up to 34% smaller file sizes compared to JPEG and up to 26% compared to PNG. Auto-compress: Check a box and every new image you upload will automatically be compressed to your preferred lossy / lossless settings. Bulk compression: Compress every existing image on your site with the press of a button. Restore original: Gone too far? Revert images back to their original in one click. Retain EXIF image data: Check a box to retain EXIF image data during compression. Lazy Load: Webpages load much faster by loading web parts gradually, when they’re needed vs simultaneous loading of everything, all at once [Premium]. Delete orphaned images: Identify and delete unused images from your WordPress website, saving disk space [Premium]. Delete unused image sizes: WordPress creates multiple sizes for every uploaded image causing the uploads folder to become bloated. Scan for image sizes not in use and remove them to save further disk space [Premium]. 3. CLEAN AND OPTIMIZE THE DATABASE Cleans-up database tables, post revisions, auto draft posts, trashed posts, spam, trashed comments and more. Choose what to optimize or it’s one click to clean out the lot. Schedule clean-ups: So you can set and forget. Choose from daily, weekly, fortnightly or monthly. Flexible clean-up schedules: You may wish to optimize database tables more frequently than you remove unapproved comments (for example). Choose the specific time and day when tasks should run [Premium]. Retain a set number of weeks’ data during clean-ups: Just in case you need to retrieve something. Back up before clean-ups: If you delete something you shouldn’t, restore it in a couple of clicks with UpdraftPlus. Power tweak – Turbo boost for WooCommerce: Unique to WP-Optimize, this power tweak boosts performance by replacing a slow query in WooCommerce with two much more efficient queries. E-commerce sites transacting high numbers of orders stand to gain here [Premium]. Power tweak – Boost performance by indexing the postmeta table: This unique power tweak works by allowing the WordPress postmeta table to be indexed, improving performance [Premium]. 4. MINIFY AND COMBINE HTML, CSS AND JAVASCRIPT Minify in just one click: Minifies HTML, JavaScript and CSS. Toggle on or off or customise each one under ‘settings’. Customise minification: Minify only (removing unnecessary code e.g line breaks and white spacing) or minify and merge. Apply the same or different settings to HTML, CSS and JavaScript. Asynchronous loading: Choose non-critical CSS and JavaScript files to load in the background and independently of other resources e.g. analytics or pixel scripts. Loading asynchronously eliminates render blocking and improves page speed. Exclude files from being minified: Specify CSS and JavaScript files to exclude from minification. Optimize fonts: Optimize Font Awesome and Google Fonts. Inline the font files, inherit from CSS settings or load CSS / Javascript asynchronously instead. Preload assets: WP-Optimize visits each web page on your site so the code is minified and preloaded for real life users, right from their very first visit. Preload key requests: Recommended by Google to improve page speed times. Critical resources (things like font files) get loaded first, so the page loads much faster. WHY WP-OPTIMIZE? It’s brought to you by TeamUpdraft, the team behind the world’s most trusted backup, migration and restoration plugin. It’s easy to use. It packs a punch for a free plugin.
