  • Network performance issues
    The result of communication and high data volume issues
  • Slow running jobs between different SAP systems (for example ERP and BW)
    Indicated by high roll wait time in the ST03 monitor.
    In this scenario a job that is running between SAP systems can take a long time to complete on the target system.
    This can be an application, hardware or database specific issue.
  • Unavailable RFC resources
    Individual RFC resources are overutilized on the target system which can generate high wait time.
  • A misreported response time which is not related to an actual performance issue, but is bug related in manner.
    In this case the response time will be unrealistically high.
