Some advanced app servers are optimized with jni native code to improve scalability and therefore don t offer a good comparison between standard i o and nio 为了提高可伸缩性，一些高级的应用程序服务器是用jni本机代码优化的，因此它们没有提供标准i / o和nio之间的很好比较。
As much as we d like to believe otherwise , compilers are generally better than humans at making code optimization decisions , especially on modern risc processors 正如我们在其它方面愿意相信的那样，在作出代码优化决定方面编译器通常比人做得出色，在现在的risc处理器上更是如此。
