Category product count loading issue

[akhileshpatel-dev]

Preconditions and environment

Magento Version 2.4.8-p1

Issue Summary

The Magento core class Magento\Catalog\Model\ResourceModel\Category\Collection::loadProductCount() does not handle large datasets efficiently.

In my case, there are 800+ categories, each containing 500–600+ products. When accessing the Admin > Catalog > Categories page, the system gets stuck while trying to load product counts, resulting in excessive load times.

Highlighted function is responsible for this issue

Steps to reproduce

Steps to Reproduce

• Log in to the Magento Admin panel.
• Create more than 500 categories.
• Assign 500–600+ products to each category.
• Navigate to Catalog > Categories in the Admin panel.

Expected result

The Categories page in the Admin should load quickly, similar to environments with a lower number of categories and products.

Actual result

The page takes more than 3 minutes to load, with the interface continuously showing the loading spinner, significantly affecting usability.

Quick work around to disable count query.

Plugin

<type name="Magento\Catalog\Model\ResourceModel\Category\Collection">
        <plugin name="category_product_count_load" type="YourCompany\ExtensionName\Plugin\Collection" sortOrder="1" disabled="false"/>
    </type>

<?php 
namespace TeamMB\DataMigration\Plugin;

use Magento\Framework\App\RequestInterface;

class Collection
{
    public function __construct(private RequestInterface $request)
    {
        $this->request = $request;
    }

	public function beforeLoadProductCount(\Magento\Catalog\Model\ResourceModel\Category\Collection $subject, $items, $countRegular = true, $countAnchor = true)
	{
		$routeInfo = $this->getRouteInfo();
		if ($routeInfo['route_name'] == 'catalog' && $routeInfo['controller_name'] == 'category' && ($routeInfo['action_name'] == 'edit' || $routeInfo['action_name'] == 'new')) {
			return [$items, $countRegular, false];	
		}
	}

    protected function getRouteInfo(): array
    {
        return [
            'route_name' => $this->request->getRouteName(),
            'controller_name' => $this->request->getControllerName(),
            'action_name' => $this->request->getActionName()
        ];
    }
}

Note : Above solution is just quick workaround not a fix,

Thanks
