在不牺牲简单性和可移植性的情况下，很难在划分的语言解释器中实现良好的性能。这是由于字节码对本机代码的动态翻译（“正式汇编”）的复杂性，这是由高性能解释者普遍使用的机制。我们证明，一些简单的技术使创建高度创建的技术是可能的 - 可以在某些数值计算中获得优化C的性能的可携带动态翻译器。基于此类技术的翻译人员可以提供可观的性能，而无需牺牲较慢的“纯”字节码解释器的简单性或可移植性。
Achieving good performance in bytecoded language interpreters is difficult without sacrificing both simplicity and portability. This is due to the complexity of dynamic translation ("just-in-time compilation") of bytecodes into native code, which is the mechanism employed universally by high-performance interpreters.We demonstrate that a few simple techniques make it possible to create highly-portable dynamic translators that can attain as much as 70% the performance of optimized C for certain numerical computations. Translators based on such techniques can offer respectable performance without sacrificing either the simplicity or portability of much slower "pure" bytecode interpreters.
