When the system is nearly at its peak, the users may get impatient with slow response time.

当系统几乎达到峰值时，用户可能会难以忍受缓慢的响应速度。

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。
