This article describes how you can detect Presta Shop modules that have an adverse effect on your website’s performance.

Here Are Some General Recommendations

Many developers ignore the impact modules can have on a server, even when the vast majority are not malicious. For example, improperly designed modules can prevent a site from having:

  • Trustworthiness
  • Execution
  • Security

Module reputations are very important because of this. Before you download and install a Prestashop AP and module, take a look at the reviews. What sort of reviews have been written (or is there an absence of reviews)? Take caution then.

Search for a module using the following search terms (replace module with the name of the module):

  • Is there a problem with modules?
  • Module performance is described here.
  • “Membership security in modules”

A suspicious module may have a similar reputation, better support, or better performance to another one.

These sections discuss the various types of modules most commonly associated with server performance.

Manipulating Images With Modules

Perhaps a module that allows batch cropping and resizing would be useful. In contrast, when back-office images are processed on a web server, the processors can be strained considerably.

Whenever you are using a module to manipulate images, remember the original image size. Reduce the image size on your local computer to a web-safe size before uploading to the server.

Products Related To These Posts And Modules

The best way to offer customers suggestions is to make them aware of products based on what they’ve looked at. That’s what makes online shops successful. The functionality of a module can normally be implemented by using one of two methods (also true of blogs that display related posts):

  • Preprocessing related products and caching copies of them in the cache is the most appropriate method. Applications can generate content faster if they use the cached copy.
  • On each page, a new custom list of related products is presented. Generally, this is not the preferred method.

A module’s method for generating related content should be identified. This can adversely affect the performance of your site.

Logging Modules For Auditing

It may seem logical to log every single activity that occurs on a website. If that’s the case, you’d be able to find out what went wrong, wouldn’t you? A website and its server can be greatly slowed down by overlogging, which can result in huge database tables.

When trying to identify the cause of a problem in a log, you have to sift through all of the irrelevant information. Such tasks require high processing power. Logging audit data is necessary, but keep it to a minimum and remove old logs after a while. In this way, you will prevent your database tables from growing unwieldy.
