Prestashop Memcached / APCu - Better cache

Benefits for Merchants

Behind the creation of this module lies our years of experience in maintaining a Redis solution, which has helped countless stores resolve performance issues. However, we are aware that not all servers can handle the requirements of connecting to Redis. For this reason, this module was created—as an accessible alternative that utilizes standard technologies such as APCu and Memcached, yet delivers performance quality far exceeding the default caching mechanisms available in the core. Our solution fundamentally differs from the built-in cache, as it was developed based on knowledge and hundreds of customer reports from recent years. Many of them struggled with issues where the default core cache failed due to flawed memory management and conflicts with third-party modules. Leveraging this knowledge, we developed a comprehensive set of intelligent conditions that ensure correct and stable cache operation for critical store elements, such as Webservice / API, payment and order processes, stock management, and product data, eliminating the risk of errors and mismatched data.

- Dramatically improve page load times and overall store performance by up to 70%

- Significantly offload your database by serving cached content, reducing query count and preventing database overload during peak traffic periods

- Increase site stability and avoid costly 500 errors during traffic spikes or sales events by serving cached pages instead of overwhelming your server

- Better cache invalidation ensures customers always see up-to-date product information

- Fine-tune cache settings for specific modules, controllers, or SQL queries with granular control

- Reduce abandoned carts with faster page loading and improved user experience

- Handle high traffic periods more efficiently without performance degradation

- Save on server resources and potentially hosting costs through optimized resource utilization

- Automatic cache refresh when products are updated, ensuring data consistency

- Compatible with all platform versions from 1.7.0 onwards, ensuring future-proof investment

- Easy-to-use interface that doesn't require technical expertise to configure

- Advanced caching algorithms that learn from your store's usage patterns

- Reduce bounce rates and improve SEO rankings with faster page loading times

- Lower cart abandonment rates by eliminating frustrating wait times

- Handle traffic spikes during sales events without performance issues

- Automatic cache management that requires minimal maintenance after initial setup

- Solve critical multistore caching issues with proper cache separation by shop ID, preventing data conflicts and ensuring each store operates independently and efficiently.
