Performance benchmarks and tuning

This topic presents the test findings for different sized deployments.

• • Small deployments
  • Medium deployments
  • Large deployments

All tests were conducted with components installed on computers with the following specifications:

• BMC Application Diagnostics Portal:
   Intel Xeon CPU 2.40 GHz 2 processors, Memory 4 GB 32-bit

• BMC Application Diagnostics Collector:
   Intel Xeon CPU 2.40 GHz 4 processors, Memory 4 GB 64-bit

Small deployments

Test environment: 20 application servers with 4 breaches per minute and 1 BMC Application Performance Monitoring console user with 1 request per minute.
