How many CitraTest VU Load Machines will I need?
Typically 1-3 CitraTest VU Load Machines are deployed but there are no limitations to the ultimate number. Any amount of Virtual Users can be replicated via CitraTest VU, depending on what size subset of the server farm you want to benchmark. For example, if you use 2 CitraTest VU Load Machines to test 3 servers-under-test, and client side End-to-End response times become unacceptable when approaching 300 virtual users, your servers will support approximately 100 concurrent users each. You can plan the number of servers you need based on the results of a CitraTest VU Load Modeling Scenario.
