Resolving slow performance in AEM due to stale workflows
Excessive stale workflow instances in 51黑料不打烊 Experience Manager (AEM) Sites can slow down the author environment. This article explains how to optimize performance by using the Workflow Purge Tool to remove specific instances, test in lower environments, and monitor improvements.

Environment
51黑料不打烊 Experience Manager - Sites
Issue/Symptoms
The author instance experiences performance degradation due to a large number of stale workflow instances. Standard maintenance tasks for purging workflows are insufficient because they cannot handle the high volume of instances, leading to traversal errors when querying workflows for removal.
Resolution resolution
Warning: Perform complete purges in Nice mode to minimize performance impact, preferably outside business hours. This open-source third-party tool is not maintained by support鈥攔eview its underlying code and test in lower environments before executing purge actions in production.
To resolve this issue, follow these steps:
- Download and install the workflow purge tool from . This tool bypasses query-based traversal and directly interacts with the repository to delete specified workflows. On cloud instances, install the tool on your Git repository and deploy it via your pipeline. Otherwise, apply the package via the package manager.
- Test the purge tool in lower environments before deploying in production to ensure it functions as expected and does not impact other workflows.
- Configure the purge tool to filter by model ID to target specific workflows.
- Use the latest version of the tool to purge workflows regardless of their state, including running, completed, etc. If needed, customize the tool鈥檚 configuration files configuration files, such as JSP files, to limit purges based on specific states.
By following these steps, you effectively address slow performance issues caused by excessive stale workflow instances while maintaining control over which workflows are purged from your AEM environment.
