Disable Adobe Commerce Banner output to improve site performance

This article provides a fix for low site performance. Low site performance can be caused by the Magento_Banner module being enabled but not used. Disabling the module output can improve site performance. Review the article for resolution steps.

Note: If you use the Adobe Commerce Banner functionality, see the High throughput AJAX requests cause poor performance article in our support knowledge base for recommendations on how to avoid performance issues caused by excessive Ajax requests.

Description description

Environment

Cause

The Magento_Banner module is enabled, but not used.

To check if this is the case:

For Adobe Commerce on cloud infrastructure 2.2.x:

If you do not see the Banners option under Content > Elements, it means that you have already applied the recommendations from this article.

For Adobe Commerce on cloud infrastructure 2.3.x and newer (the functionality was renamed in v 2.3.x):

If you do not see the Dynamic Blocks option under Content > Elements, it means that you have already applied the recommendation from this article. To see the banners option again, reverse the process.

Cause

When the Magento_Banner module is enabled, Adobe Commerce sends Ajax requests from the storefront to the server to get the banner information. These Ajax requests have a performance impact, especially in high-load (high-volume and high-traffic) conditions. If the functionality is not used, it is recommended that you disable the module output. It is not recommended to disable the module, because of the dependency issues.
