Why do we really need multiple netty boss threads

[chunhodong]

In single ServerBootStrap, What's the effect of increasing boss thread?

@chunhodong in the future please use stack overflow for questions as this is an issue tracker.

Anyway let me answer this one quickly... It only makes sense to use more than 1 when you bind multiple times (to different ports) or re-use it between different ServerBootStrap. Often it is good enough to just use the same group for boss and worker
