以我的经验来看，导致程序运行速度慢得罪魁祸首可能就是某个内部或嵌套循环，也可能是对第三方库函数的调用。

In my experience, it will usually be a particular inner or nested loop, or a call to some third party library methods, which is the main culprit for running the program slow.

更重要的是，对构建3运行的并且随后不在循环中重新运行的测试可能会错过构建4或之后引入的缺陷。

More importantly, tests that were run on build 3 and not rerun later in the cycle may have missed a defect introduced in builds 4 or later.
