rocketmq顺序消息，消费很慢 rocketmq问题

生产者
public void start() {
        producer = new DefaultMQProducer(groupName);
        producer.setNamesrvAddr(namesrvAddr);
        try {
            producer.start();
        } catch (MQClientException e) {
            log.error(e);
        }
    }

    public void send(Object orderId,Message msg) {
        try {
            SendResult sendResult = producer.send(msg, new SelectMessageQueueByHash(), orderId);
            log.debug(sendResult.toString());
        } catch (Exception e) {
            log.error(e);
        }
    }
消费者
public void start(){
        try{
            consumer = new DefaultMQPushConsumer(groupName);

            consumer.setNamesrvAddr(namesrvAddr);

            consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);

            consumer.subscribe(consumerTopic, consumerTag);

            consumer.registerMessageListener(new MessageListenerOrderly() {
                @Override
                public ConsumeOrderlyStatus consumeMessage(List<MessageExt> list, ConsumeOrderlyContext consumeOrderlyContext) {
                    consumeOrderlyContext.setAutoCommit(true);
                    for (MessageExt messageExt : list) {
                        listener.onMessage(messageExt);
                    }
                    return ConsumeOrderlyStatus.SUCCESS;
                }
            });
            consumer.start();
        }catch (Exception e){
            log.error(e);
        }
    }
1.第一次发送，消费者很久才开始消费，应该1-2分钟才开始消费
2.消费者返回的Susccess但感觉一直没有返回成功，一直还在消费
3.消费速度很慢，消费者逻辑就一个打印信息，基本上1秒钟才消费2个消息
