Rather than strive for optimization of any function, a large system can only survive by "satisficing" (making "good enough") a multitude of functions.

与其费劲将任一功能做到最优，不如将多数功能做到"满足"（使“恰好”），这才是大型系统的生存之道。

As a rule, code compiled with full optimization can be difficult or impossible to debug, making it very difficult to identify bugs that may be causing the system to function incorrectly.

通常，经过完全优化的编译代码很难或者几乎不可能进行调试，这就加大了发现那些造成系统功能错误所在的难度。
