It is also recommended to backup your site before making any changes.
Keep in mind that this process may affect the performance of your site, so make sure to check the site after the process and make any necessary adjustments.
It is also recommended to use this in combination with a debugging tool like xdebug to get more detailed information about the performance of your site.
The debugging mode can be useful in identifying issues with your site and troubleshooting them. Profiling can be useful to identify slow parts of your site and optimize its performance.
