The IBM XL C compiler is a very good optimizer, and as a result, the C algorithm delivers superior results to a simple unoptimized assembly language implementation.

IBM XL C 编译器是一个非常好的优化器，结果是 C 算法的性能要比未经优化的汇编语言实现的性能好很多。

The Ruby source code is compiled into native machine code (same process as we do at runtime with the JIT compiler), so it's also a good way to obfuscate the source code.

因为Ruby源代码已经编译成了原生机器码（正如我们使用JIT编译器在运行时所做的一般），因此这也是混淆代码的一个不错的方式。

This was a good thing, all of a sudden, instead of being constrained to 3 index registers, the compiler could use 6 of them.

这是一件好事，所有的突然，而不是被约束至3个索引寄存器，编译器可以使用它们中的6个。
