简介
WAST是一个高性能Java工具集库包，包括JSON、YAML、CSV、HttpClient、JDBC和EL引擎.
下面是单独对WastEl性能测试，测试环境window10 处理器i5 JDK1.8 单线程 idea工具(服务器配置性能中等)

结论
- 解析模式下执行静态表达式在无缓存的情况下每秒1.5千万次（注包含解析过程）
- 解析模式下执行静态表达式在有缓存的情况下每秒1.6亿次（只解析一次）
- 编译模式下包含4次加法运算的动态表达式每秒最高3亿次基本上和java代码每秒运行的次数持平

第三方测试目前只加入过express-benchmark （作者闲.大赋），结果有两月没更新了，无奈自己贴下个人运行的结果
public class Test {
public static void main(String[] args) throws Exception {
org.openjdk.jmh.Main.main(args);
}
}
