How to check which file slows down the page

[domorodecmezilidmi]

Hi guys I would like to ask you for advice. In the last step where customer confirm order so after clicking on this button then it takes really long time to see final screen with confirmed order. Could you pls help me how can I truck which file can make this mess? We have tested it yesterday and it took around 25s to process this last step and one client told me that she saw white screen with some blue error note. Thank you.

My guess it it might be related to order confirmation email, you can try to disable the email delivery to see if that changes.

 

otherwise, you may need to enable _PS_DEBUG_PROFILING_ in file /config/defines.inc.php to see where it takes so much time.

 

define('_PS_DEBUG_PROFILING_', true);
