To see the opinion of your prestashop installation on its own speed, there is a function called “Profiling” which can be turned on for debugging purposes, or to just get the odd view on how fast your web server may be.
In order to activate this, change a file. The path is this, from your installation directory:
/config/defines.inc.php
In this file, look for this entry:
define(‘_PS_DEBUG_PROFILING_’, false);
Set this value to “true”, and save.
Now a bulk of data will be displaye under each page, in both front office and back office. Just scroll down to see it.
