In this article, we describe how you can detect PrestaShop modules that affect the performance of your site.
The Following Recommendations Are General
The vast majority of modules are not malicious, but many developers do not consider the impact they can have on a site and its server. For example, improperly designed modules can prevent a site from having:
- Reliability
- Performing
- Protection
Because of this, modules’ reputation is extremely important. Check the reviews of a Codice SDI and module before you download it and install it. Are the reviews consistently negative (or are no reviews available)? Then proceed with caution.
For researching a module, you can use the following search terms (replace module with the module’s name):
- “Problems with modules”
- “Performance of modules”
- “Security in modules”
It is often the case that there is a similar module with a better reputation, support, or performance if you are suspicious about a particular module.
Various types of modules most commonly affect the performance of servers are discussed in the following sections.
Modules for Manipulating Images
An image module that allows for cropping and resizing of batches might seem convenient. On the other hand, when a web server is used to process back-office images, the load on the processors can be significant.
Remember to keep the original image size in mind if you are using an image manipulation module. Prior to uploading to the server, reduce the image size to a web-safe size on your local computer.
Posts and Modules Related to Related Products
It is important to offer customers suggestions based on the products they have viewed or are currently viewing. This is a key component of the success of online shops. Normally, modules implement this functionality by using one of two methods (this also applies to blogs that generate related posts):
- The first, and most suitable, method is to preprocess related products and cache copies of them in the cache. By using the cached copy, applications can generate page content more quickly.
- Secondly, a new customized list of related products is offered for each page. This method is less preferred.
Identify the method that a module uses for generating related content. Your site’s performance can be greatly affected by this.
Modules for Audit Logging
The idea of logging every single activity that takes place on a site may seem logical. In that case, you will be able to find out what went wrong, right? Overlogging, however, can result in huge database tables, which slow down a website and its server far more than any potential diagnostic benefits.
To find the root cause of a problem you have to sift through all of the irrelevant data in the log to find any relevant data. Processor-intensive tasks are necessary to process this data. When audit logging is required, keep the amount of data logged to a minimum and make sure to purge old logs after some time has passed. By doing so, you will avoid database tables becoming unwieldy.
