Shipping module vs execution time

[Sonriente]

Hello.

 

I've developed a shipping module that works fine except the execution time.

When the module is enabled the cart/checkout pages are loaded up to 20-30 seconds.

The module communicates with 3-d party API, but the average execution time of the code that communicates with external service is 0.5-1.5 sec. So, there is no any problems with the external service.

I've performed an investigation and found the following:

The problem is caused by the fact the getOrderShippingCost function is called several times (randomly, from 2 to 10) during the loading of the cart page.

I don't understand why it is executed several times and how to avoid this issue. Is it a bug in my code or bug in Prestashop?

The backtrace is attached to this message.

 

Any ideas will be appreciated greatly.

Hi there,

 

I'm running into the same issue. In fact, the method in our module is being called 4 times. Anyone found any solution or explanation why this happens and how to avoid the multiple-calls?

 

We're thinking about placing time counters or any other kind of similar system, but of course it's not a good practice.

 

Regards!
