There is no direct footprint benefit because each JVM still has a copy of the AOT executable but there are memory and CPU savings from being able to reuse this code rather than repeat the compilation.
因为每个JVM仍然拥有AOT代码的拷贝,所以这种实现方式对于内存使用量没有直接的好处。但是,由于能够重用 AOT 代码并避免重复编译,可以节省内存和CPU。

Depending on the compilation time and how much faster the compiled code is than the interpreted code, small changes in the number of iterations can result in big differences in measured "performance."

无论是哪一种,除非程序员有权访问类c的源代码,否则他无法预知何时会发生编译错误。
JIT compilation removed the overhead of interpretation (at the expense of some additional startup cost), but the level of code optimization was mediocre for several reasons.
JIT消除了解释的负担(以额外的启动成本为代价),但是由于若干原因,代码的优化等级仍然是一般般。

Make was the tool of choice for scripting and managing code compilation. Sprinkle in a dash of batch files or shell scripts to add automation and you had a build process.
要描述并管理代码的编译过程,可供选择的工具就是make,再加上零星几个批处理文件或是shell脚本以增加自动化程度,您的构建过程也就这样了。
Moreover, for applications with large numbers of functions and classes, enabling Psyco application-wide adds a large burden in machine-code compilation and memory-usage for this caching.
