Per traffic volume
Start with a basic system of one instance of each component type and build up the system as required, for example, when the volume of traffic to the monitored application increases.
Scaling for increased collection load
To handle increased traffic volume, deploy additional Collector instances. If traffic volume increases to the extent that more than three Real User Collector instances are required, you must deploy additional Real User Analyzer instances.

Scaling for increased processing demand
If you have deployed more than three Collector instances or if a single Analyzer cannot efficiently process all requests for statistics, dashlets, reports, and so on, deploy additional Analyzer instances. You can also deploy multiple Performance Analytics Engine instances as demands on insertion capability increase.
