How to Configure PrestaShop with Memcached for Optimal Performance

Memcached is a system that improves performance by speeding up how database websites deliver information. It works by caching various bits of data and reduces how often the site has to make calls to external sources. In other words, it makes platforms like PrestaShop work much better over the long-term.

PrestaShop working with Memcached servers makes the speed of the site better for both users and search engines. After all, systems like Google hold fast websites in higher regard meaning they will perform better in search results. It’s all part of good SEO.

Today, I’m going to show you how to configure PrestaShop to work with memcached. You’ll need to know your server’s information in order to set this up correctly.

Enabling Memcached

Scroll down to the very bottom of the Performance page. Click “Yes” for the Use Cache option.

New options will become available in the Caching section.
