Site loads slowly when config many configurable products on M2.4.0

Created by Rosa Truong, Modified on Tue, 10 Nov 2020 at 02:49 PM by Rosa Truong

Issue:

Plugin out of memory (4GB) when opening grouped products with more than 15 configurable products.

Vanilla Magento 2.4 No plugins / Default Luma Theme.

The site loads so slowly when going a product link (more than 16 config products).

Could you please check and give the solution?


Solution: 

It only happens on Magento 2.4.0 when one grouped product has a lot of configurable products; so it causes the error Memory size allocated for the temporary table.

The root of this issue is that the site has to caches a huge HTML with js.

To fix this issue, we would like to give a hot-fixe solution when using the cache lifetime to solve the problem.

We have changes this file app/code/Bss/GroupedProductOption/Block/Product/View/Type/Configurable.php 

When getCacheLifeTime is null, instead of loading html from cache, block will render  function _toHtml().

Please check and try to apply the solution and then flush the cache on your site.


If you have any other issues, please don't hesitate to contact us.
