Excessively extensive plugins with many functions and many setting options have the disadvantage that they slow down a website. When optimizing WP plugins, unnecessary functions and options that are not needed for the website in question can be removed.
Plugins are not always carefully programmed, which means that they damage the performance of the entire website. If, for example, scripts are integrated everywhere but are only required on a few pages or only in the admin area. Or images that are too large are integrated – this can all be remedied by a professional.
