Does Using Multiple Custom Modules in displayHome Affect Performance?

[Mac Story]

Hello everyone,

I have developed multiple custom modules for my PrestaShop homepage, all hooked into displayHome. These modules are designed to be repositioned via BO > Design > Positions, allowing flexibility in their placement.

Each module includes its own CSS, JavaScript, and images, and I’m concerned about whether having multiple modules with separate assets could negatively impact performance. Specifically:

Could this setup lead to slower page load times or increased server resource usage?

What are the best practices to optimize performance while keeping the modules flexible and repositionable?

Should I consider combining? or lazy-loading CSS/JS files to minimize overhead?

What’s the best approach for handling multiple images across different modules to prevent excessive loading times?

I would appreciate any insights or recommendations on how to efficiently manage this.

Thank you!

Hi, it depends of each module if it use a smarty cache.

Hello @Prestashop Addict, Can having many custom modules affect the Front Office site performance?

Yes.

Executing multiple module hooks, Loading multiple resources (CSS/JS), and rendering templates using multiple hooks will certainly impact performance.

It depends what each module does (SQL queries, webservices calls...) and if it use or not smarty cache.
