关于 IO 线程是否需要额外的线程处理在另一个项目 cicada 中也有多次讨论：

我个人的考虑是在 cim 这个场景下由于可能会存在对消息做多次处理；不能保证每次处理的效率。所以我把他的处理逻辑放到了线程池中，这样不会影响到正常的 IO。

而在 cicada 作为一个 HTTP 框架的场景下，默认是不开启额外的线程处理 IO 业务，但也打算新增一个注解，加上之后默认也是由内部线程池处理。

所以我认为在大多数场景下都需要把 IO 线程独立起来，避免出现极端情况阻塞 IO 线程导致吞吐量降低。

顺便还有个小问题：
什么时候handle该使用@Sharable注解，而非每个Channel使用不同的handle

这个建议先 Google 了解下。
