Issue/Introduction

Performance Issue. Timesheet related processes/actions are taking longer than usual time to trigger. With delay in processes again after the 15.9.3 upgrade. Upon investigation it seems to be a bit different this time as I believe the main culprit here is with the Action Execution Pipeline, it is continuously running and very slow in processing. It takes hours to trigger an action and even after action is triggered it is taking hours to mark the step as finished.

Steps to Reproduce:  

1. A first process runs and completes at 3:12 AM EST. This process auto-approves the timesheet at the first level of approval and sends an action item to the next level of approval.
2. However, the next level of approval action items is still being generated 6 hours after the process was completed.

Expected Results: Processes should trigger and steps complete in reasonable time. 

Actual Results: It takes hours for process to trigger an action item and get to finish state.
