The work of capacity management is finding a balance between the unused expense of having too much idle capacity against the risk of reputation - damaging problems from not enough capacity 在从压力测试下得到的当前压力（实际需求）和可用容量不同的地方在于真实的存在的容量-可增长的峰值储备总计或者处理需求不断变化的能力。

The difference between the current load ( the actual demand ) and usable capacity from load testing is the real reserve capacity ? the amount of " head room " for growth or the ability to handle variation in demand 在从压力测试下得到的当前压力（实际需求）和可用容量不同的地方在于真实的存在的容量-可增长的峰值储备总计或者处理需求不断变化的能力。
