所有经过测试的JS引擎都是解释器，并且运行资源有限。
bench-v8源代码在QuickJS测试档案（tests/bench-v8目录）中提供。
在Fedora 21上使用gcc 4.9.2编译所有程序。它们在3.2 GHz的Core i5 4570 CPU上运行。
可执行文件尺寸是指运行引擎所需的所有资源(除了系统C库)的大小。
- QuickJS: version 2019-07-09, qjs executable, x86, 64 bits, compiled with -O2.
- DukTape: version 2.3.0, duk executable, x86, 64 bits, compiled with -O2.
- XS: version 8.8.0, xst executable, x86, 64 bits, compiled with -O3. The engine cannot correctly run the RegExp test, so it was disabled.
- MuJS: version 1.0.6, mujs executable, x86, 64 bits, compiled with -O2. The engine cannot correctly run the RegExp test so it was disabled. JS_STACKSIZE and JS_ENVLIMIT were increased to 32768 to run EarleyBoyer.
- JerryScript: git version 2b8c4286, jerry executable, x86, 64 bits. The engine could not run EarleyBoyer, RegExp and Splay.
- Hermes: version 0.1.0, 64 bit Linux binary downloaded from here. The benchmark was run with the -O option (=enable expensive optimizations).
- V8: version 7.7.289, Linux 64 bit executable downloaded from here.
运行基准测试，可以按需添加其他Javascript引擎。
