StateMirror: Scalability

Sample test configuration

• StateMirror servers: P4 2.7GHz, 256MB RAM
• Local network: 100mb
• Session state data size: 2kb
• Number of clients (session objects): 1440
• Request frequency: 480 requests per second (every 3 seconds, every web user sends HTTP request that causes page re-generation and one session state "get-set" cycle)
• Session state change: on every "get-set" cycle
• Client caching: enabled
• Number of session state data copies: 2

Test metrics

• CPU load: average StateMirror Server CPU load
• Network load: local network utilization
• Service memory usage: total memory used by StateMirror service
• Memory allocated: memory allocated by .NET for StateMirror service
