> Our profiling shows that a lot of apps are neither CPU nor memory or network bound. Instead they waste a lot of time waiting for lock in MessageStore. That happens in netty threads. 
> We should be able to put messages into queue and then process them in other set of threads. 
> It has to be configurable because adding another thread level will introduce additional overhead.
