+
+测试细节
+------------
+
+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。
+
+*   [QuickJS](https://bellard.org/quickjs): version 2019-07-09, qjs executable, x86, 64 bits, compiled with -O2.
+*   [DukTape](https://duktape.org/): version 2.3.0, duk executable, x86, 64 bits, compiled with -O2.
+*   [XS](https://github.com/Moddable-OpenSource/moddable): 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](https://mujs.com/): 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](http://jerryscript.net/): git version 2b8c4286, jerry executable, x86, 64 bits. The engine could not run EarleyBoyer, RegExp and Splay.

+运行基准测试，可以按需添加其他Javascript引擎。
