M2.3.7, v1.1.7: The server load goes up (100%) when enabling the module

ISSUE:

After enabling the Matrix View module, the Server Resource all goes to 100%. After disabling it slowly goes down (<5% as normal)

SOLUTION:

As the module has not been optimized for websites with a great number of child products, Mysql will be failed when there are too many requests at the same time occurring on your site.

To temporarily improve your server, please edit the file app/code/Bss/ConfigurableMatrixView/Model/ResourceModel/Product/Type/Configurable.php as below:

Or download the file attached below to override the current file on your site. 

Kindly note that our solution only works in case the Multi-Source Inventory (MSI) of Magento default is disabled.
