Include CPU Estimates for Service Dependencies

The components providing user entry points require support from other Java Enterprise System components. As you continue to specify performance requirements, add the performance estimates required for supporting components. The type of interactions among components should be detailed when designing the logical architecture, as described in the logical architecture examples in the section Example Logical Architectures.

Table 5–2 CPU Estimates for Supporting Components
