Typical causes of performance problems

Typical problems that may affect system performance include:

• Inefficient or large, complex voice response applications

  The most common cause of performance problems is inefficient voice response applications. Verifying the efficiency of voice response applications is a critical step to resolving problems. The person or team responsible for developing voice response applications is responsible for checking application efficiency.

• Excessive, ill-timed, or unnecessary Avaya IR system processes external to voice response applications

  External processes are those required for system operations outside of voice response applications or for providing data to the voice response application. Since processes required for data access are driven by voice response applications, you may need to make changes to the applications to fix these performance problems.

• Voice processing that exceeds the capabilities of the system

  If current voice processing exceeds the capabilities of your system, you will need to consider adding another system to handle the increased demand. However, there are actions you can take to reduce the load on your current system. This section explains how to reduce load.

• Bottlenecks or increased CPU usage caused by inadequate LAN access or incorrect LAN configuration

  If your Avaya IR system receives voice response functions through the LAN, all speech LAN functions should be on their own LAN segment. If you are using touchtone and recorded speech, a separate segment is not required. You also may benefit from placing the Avaya IR system on a separate LAN segment if voice response applications frequently access remote databases. If CPU usage is high, make sure that all configuration settings are correct.
