The following types of changes may result in performance problems:
Natural Language Speech Recognition (NLSR), Proxy Text-to-Speech (PTTS), Avaya Recognizer, VoiceXML, TN3270 host (combined with JDBC or TN3270 host, or JDBC alone) place a heavy load on the system. The use of NLSR can dramatically change performance.
When you make changes to your system configuration or to voice response applications, be sure to monitor the system for performance problems.
