Performance issues caused by excessive Ajax requests

This article provides a patch for the known Adobe Commerce performance issue caused by excessive Ajax requests. The issue was fixed in Adobe Commerce 2.3.4.


Adobe Commerce might be sending redundant Ajax requests from the storefront to the server to get the banner information and customer information. These Ajax requests have a performance impact, especially in high-load (high-volume and high-traffic) conditions. So if the Banner functionality is not used, it is recommended that you completely disable the Adobe Commerce Banner module output and apply the patch to improve retrieving customer information.
