What is the best configuration for 600 virtual users? (4277723)

Benchmarking databases ( sybase , oracle, db2, ms-sql) on VM Ware with a total of 600 virtual users. This will be for different test cases.
What would be the best configuration including the number of Agents for Benchmark Factory?

For optimal configuration, that really depends on what workload you are testing with. If the scenario is doing a more CPU intensive test, then the Agent workstations combined CPU power needs to exceed the CPU power of the server machine. CPU is bottleneck on the Agent(s) that is hit the majority of the time. The best practice is to monitor the Agents as the test is running to see how things are the resource levels of the Agents. There is no configuration template in the exact number for agents for 600 virtual users.
