摘要

Java Native Access (JNA)是为了减轻使用Java Native Interface (JNI)编程的负担而提出的。JNA允许程序员在不编写任何JNI代码的情况下调用本机函数。但是，JNA存在一些性能下降。为了克服这一问题，本文对JNA源代码进行了修改，并将LLVM JIT编译器集成到JNA中以提高性能。我们的实验通过调用具有不同类型和数量参数的本机函数实现了大约8%到16%的性能改进。此外，我们的设计是一种非传统的使用运行时编译器的方式，我们遇到的挑战可能会帮助其他研究人员面对类似的情况。

Improving performance of JNA by using LLVM JIT compiler

Java Native Access (JNA) has been proposed to alleviate the burden of programming in Java Native Interface (JNI). JNA allows programmer to call native functions without writing any JNI codes. However, JNA suffers from some performance degradation. To overcome this problem, in this paper, we modify the JNA source code and integrate the LLVM JIT compiler into JNA to improve the performance. Our experiment achieves about 8% to 16% performance improvement for calling a native function with different types and numbers of arguments. Furthermore, our design is a non-traditional way of using the runtime compiler, and the challenges we encountered may help other researchers to face the similar situations.
