Dynamic and ahead of time optimization for JavaScript programs
https://doi.org/10.15514/ISPRAS-2014-26(1)-10
Abstract
The paper is dedicated to performance improvement of JavaScript programs. In this work we examine the specifics of dynamic optimizations in JIT-compiler for JavaScript, and how the performance of such optimizations can be improved. Also we propose a method for ahead-of-time (AOT) compilation of JavaScript programs, and for saving them as a bytecode. This method allows reducing startup time of applications by moving the optimizations to AOT phase. The proposed methods were implemented in open-source WebKit library, and resulted in significant performance gain for popular JavaScript benchmarks on ARM platform.
