不知道该起个什么样的标题来记录这句话，看到这句话时感觉写的非常好，想记录一下：
Performance problems are usually the result of contention for, or exhaustion of, some system resource
性能问题通常是一些系统资源被争夺或者是被耗尽的结果！
Performance problems are usually the result of contention for, or exhaustion of, some system resource
--===========================================
从另外的角度来讲：性能问题来至于：
Performance problems generally result from either a lack of throughput, unacceptable user/job response time, or both. The problem might be localized between application modules, or it might be for the entire system.
