Once the non-functional requirements of a system (load capacity, average response time, peak-load response time, and so on) have been met the application can be deployed and the customer is satisfied.
只要满足了非功能性需求(负载能力、平均响应时间、峰值响应时间等)，应用程序就可以部署，用户也会觉得满意。
Managed threads within the application server directly influence and dictate the server's capacity for processing work (Figure 2 illustrates this scenario).
