   Hi @nowinkeyy,
   
   I read your proposal and have some questions.
   
   1. Under normal circumstances, the messages of same queue are ordered in the commitLog. So your improvement is just to execute the dispatcher asynchronously? It seems that the batch write you describe will not work in most cases.
   2. I don't see anything about recovering from fault in your proposal. eg. Where to start rebuilding cq after broker is down and restart.
