Fastcache by Host.it vs Image Optimizer, Resizer and CDN – Sirv

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.

What our users say ★★★★★ “We’ve halved the load time on mobiles of a site that we had already done quite a bit of work on to get image sizes down.” @martingfisher ★★★★★ “So far the best CDN plugin for WordPress. Please, never disappear!” @mavenickster ★★★★★ “I was looking for a CDN fast and easy (no need to code)! Sirv is the best – Just upload your photos to your WordPress library and voilà “roulez jeunesse!!!” (French expression). Very good service!” @disconance ★★★★★ “Sirv is fantastic! I have a lot of images on my website, and most of them are large, which resulted in slow site speeds, even with a CDN. What I love about Sirv is that they offer a CDN service, but also dynamically resize images based on the user’s browser/device, and serve the right file type. It has meant HUGE speed improvements on my website.” @basellen Optimal format (every time) Google loves next-gen image formats for SEO, but it’s a pain to convert all your images and keep track of them. Sirv solves that. It automatically delivers images to each user in the most optimal format. Usually that’ll be AVIF or WebP and the filesize is dramatically smaller, so Google will reward you with better search ranking. Sirv’s intelligence always serves the smallest possible file format to each users’ browser. It is 100% automatic. Plus, images are automatically scaled down to the suitable width/height and they’re lazy loaded, so you’ll really have the best possible image solution for WordPress.
