现业务是接收http post请求并必须在15毫秒内返回，
我的实现思路：
1：首先netty接收完数据，验证contenttype等header信息再将post的数据protobuf反序列化成对象(必须)，
2：然后将对象传入到某个方法，
3：该方法必须定时10毫秒完成，如果没有完成就直接返回null和请求的header
具体实现是：
netty 主线程接收完数据转成request对象传到1号线程池里面，1号线程池验证对象和反序列化，传给2号线程池并wait10毫秒然后直接得到2号线程池的返回对象，有就有，没有就是null，然后再channel返回。2号线程池主要处理业务生成对象供1号线程池调用。

现用tomcat同样配置执行是4000qps，超时率为4%; netty是1000qps,超时率为5%;
netty：

现需要qps达到1w以上。希望收到你的回答或demo。谢谢
ps: akka ，但觉得个人写future和他差不多吧。
