Load tests were performed by using automated scripts to determine system performance at peak capacity and to verify application scalability. These tests were run using the BMC Virtual Agent, BMC Remedy IT Service Management (BMC Remedy ITSM), BMC Knowledge Management, and BMC Atrium CMDB applications. The test model represented 250 concurrent self-service users chatting with either a virtual agent or live agent and simulated 1000 chat messages per minute.
The tests were conducted with the following software running on a single server in a virtual machine (VM):
The VM was running on VMware ESXi 5.0 with the following configuration:
End-user response times were measured in seconds based on how long it took the application to load key forms and pages. The BMC Virtual Agent application operated as expected with no performance issues.
The following graph shows the response time to load initial pages and to log on to the self-service portal and support agent console. It also shows the average time to submit a question to the virtual agent, query the artificial intelligence markup language (AIML) and BMC Knowledge Management repositories, and receive a response (chat round trip).
