为什么Netty表现不佳?

jay*_*esh 0 java performance network-programming netty

我用这个例子 进行性能测试

有人说netty的表现如此之快.它可以处理1,00,000+并发请求/秒(请查看以下链接)

但是当我尝试这个例子时,它只给我107个req/sec,同时有1000个请求

ab -n 10000 -c 1000 http://localhost:8080/

给我一个建议问题在哪里

有人可以分享任何网络示例或参考突出显示netty的性能基准.

您没有丢弃请求,我将使用Siege进行基准测试并与其他类似设置进行比较.你还在使用什么样的系统?可能你还需要增加文件描述符才能生效.您还需要在进行基准测试之前配置JVM.这些方面的东西:

-server -Xms2048m -Xmx2048m -XX:+UseParallelGC -XX:+AggressiveOpts -XX:+UseFastAccessorMethods
