November 2, 2025 — In questo lightning talk esploreremo come implementare un sistema di cache basato sui transient di WordPress per migliorare drasticamente le performance e l’impatto dei siti con contenuti dinamici basati su ACF. Partendo dal problema del caricamento ripetitivo dei campi personalizzati, analizzeremo una soluzione scalabile ed efficiente che riduce le query al database fino al 70%. Vedremo come gestire automaticamente l’invalidazione della cache al salvataggio, come implementare una cache multilingua, e come ottimizzare selettivamente i campi non utilizzati.

April 27, 2023 — Partendo dal funzionamento di cache e di reverse proxy, scopriremo Varnish, una cache che possiamo affiancare a WordPress. In questo talk scopriremo come questo progetto, Open Source, ci permette non sono ti ottimizzare la velocità di caricamento delle pagine ma anche di gestire molti accessi contemporanei.

December 18, 2022 — Uno dei principali obiettivi di chi realizza siti WordPress è sicuramente l’aspetto prestazionale.

Tra i metodi più diffusi per raggiungere quest’obiettivo c’è sicuramente l’utilizzo della cache.

Tutti sappiamo, più o meno, cos’è la cache di un sito web e come funziona ma non tutti i sistemi di cache danno gli stessi risultati.

In questo talk vedremo insieme l’utilizzo dei sistemi di cache come strumento fondamentale per massimizzare le prestazioni, ridurre l’assorbimento di risorse server-side e gestire picchi di traffico importanti. Vedremo, inoltre, quali sono, secondo la mia esperienza, le migliori tecnologie Open Source di cache e un caso studio di un sito WordPress ad alto traffico.

Mais pour appréhender la performance d’un site web, encore faut-il savoir quels indicateurs collecter, comment les interpréter et les améliorer.

Quand on travaille sur un CMS comme WordPress, il est aussi important d’évaluer ce qui peut mettre en danger cette performance, et les techniques à développer pour s’en prémunir.

December 28, 2018 — WordPress makes dozens (or hundreds) of SQL queries every time it serves a page. Every single one of them involves MySQL, and many of them hit the disk. Learn how Redis can turn those hundreds of queries into a handful, speeding up your site and reducing the load on your database.
Along the way, you’ll learn about WordPress transients (a way of storing data temporarily in the WordPress database), see the world’s most technically-compliant cache, and learn secondhand about server crashes (so you don’t have to learn firsthand).
In the session, you will receive the preliminary results of experiments to evaluate the impact of Gutenberg on a site’s database load. For example, does the way Gutenberg blocks are stored or the standardization of blocks reduces the hits on the server?
In this talk, you’ll learn:

How WordPress transients work
setting up an external object cache with Redis
simple Redis monitoring

July 10, 2018 — Make your WordPress site fly with this one weird trick…except it’s more than one trick, and it’s only weird until you learn how it works. Varnish Cache can speed up information delivery by a factor of several hundred and earn you the coveted “A” in the TTFB column. This talk will provide an overview of Varnish Cache, what it is and how it works. Then we’ll explore setup and the ways you can integrate Varnish with simple WordPress sites before discussing more complex implementations, strategies for handling state, Edge Side Includes and other neat things Varnish does. HTTPS? Glad you asked. We’ll talk about that too.
