Turbocharging Your Magento 2.3: An Insider’s Guide to Navigating Database CPU Load Increases and Optimizing Search Term Performance

The Magento 2.3 upgrade has inadvertently increased database CPU load within e-commerce, mainly due to the inefficient execution of the DISTINCT COUNT query in the new Popular Search Term Cache.
