title: How to improve performance of the cleanup of the history tables of the Activity engine
body: <p>I do have an application based on the <a href="https://github.com/Activiti/Activiti" rel="nofollow noreferrer">Activiti engine</a> in version 5.22. Currently, it produces in a given time frame more history information than the history cleanup process is able to delete in the same time frame. Is there any idea how to improve this behavior?</p>
