HttpServer性能比较

在自己的本子上随便测了下几款HttpServer，环境信息就不贴出来了，主要是比对下差距。

测试内容是输出 text/plain 的 hello, world。

先说结论：Netty > Jooby > JDK HttpServer > Jersey-Netty > Jersey-HttpServer > RESTeasy-netty4 > SpringBoot。

但需要注意下，第一名的Netty吞吐是第二名的HttpServer的2.7倍，而且errors表现也很优秀。

Jersey 的 overhead 也摆在那儿，吞吐瞬间掉到 13156.38 req/sec，可见同步模型的确不擅长撑并发。

排名最后的是 SpringBoot，此前知道它性能差，没想到差成这样。
