This technical paper describes test results that demonstrate the scalability of Microsoft Speech Server 2004 Enterprise Edition to a level capable of supporting large-scale enterprise deployments.

Microsoft Speech Server’s scalability was tested in a multiserver configuration incorporating Intel® Pentium® processors, Intel® telephony boards, and Intel NetMerge® Call Manager software. The results provided here show that a 1,100-port configuration with a call completion rate of more than 1,700 calls per minute experienced an aggregate CPU utilization rate under 50%.
