This business rule runs synchronously and is the suggested configuration.\n\n## Before you begin\n\nRole required: sla admin, admin\n\n## About this task\n\nSLA processing runs asynchronously. For example, you can run this for performance reasons, such as to avoid delays when a user saves a new incident record. While the SLA engine is running asynchronously, there can be a short delay before the Task SLA records are available after updating a Task. Refresh the form to see the updated Task SLAs.\n\nUse synchronous processing to get the best user experience. Asynchronous processing mode is used only when there a performance issues.\n\n**Note:** In the 2010 engine, the **Process SLAs** business rule runs the asynchronous processing.\n\n## Procedure\n\n1.
