PrestaShop includes several debugging options including one called Debug Profiler. This allows you to see everything that is running on the page and will also give performance data such as the time it take for data to load. The following article shows you how to enable the Debug Profiler within PrestaShop 1.5.
Please make sure to create a backup before making the change to the Prestashop configuration file. This will allow you to return to a working point if needed.
