performance - 比较 Lua 和 Mono

Question

<分区>

Answer 1

您正在比较 apples to oranges . C# 是一种静态类型语言，编译为 CIL这是一种字节码语言，由虚拟机运行(或通常为 JITted )，用于 Web 和独立应用程序开发。 Lua 是一种动态类型的脚本语言，通常由解释器运行，通常作为可扩展的脚本语言嵌入到更大的应用程序中。

此外，您对基准的解释是错误的。条形图显示，与等效的 Lua 程序相比，Mono 程序的运行时间约为其运行时间的 1/10。

也就是说，这种微基准测试在很大程度上是无用的。不要相信我的话；阅读 what the Shootout itself has to say about it .你应该阅读整篇文章，但我会摘录一些有趣的引文:

"The performance of a benchmark, even if it is derived from a real program, may not help to predict the performance of similar programs that have different hot spots."

"It may seem paradoxical to use an interpreted language in a high-throughput environment, but we have found that the CPU time is rarely the limiting factor; the expressibility of the language means that most programs are small and spend most of their time in I/O and native run-time code."

"Programming languages are compared against each other as though their designers intended them to be used for the exact same purpose - that just isn't so."

长话短说:选择您的语言取决于它是否能很好地完成您想用它做的事情，它是否能让您清楚地表达您的意图，它是否能让您编写干净、可维护的代码；不是基于一些基本上没有意义的数字。
