AWSMQTT IoT核心消耗时间

Question

当前，我正在为IoT环境传感器制作原型，并使用AWS IoT Core作为消息代理。我已经完成了此设置，正如您所看到的，我将漏极频率提高到了10。

    def setupMQTTConnect(self):
        self.mqtt = AWSIoTMQTTClient(self.hostname)

        self.mqtt.configureCredentials(self.rootca, self.privkey, self.cert)

        self.mqtt.configureEndpoint(self.endpoint, 8883)

        self.mqtt.configureAutoReconnectBackoffTime(1, 32, 20)
        self.mqtt.configureOfflinePublishQueueing(-1)  # Infinite offline Publish queueing
        self.mqtt.configureDrainingFrequency(10)  # Draining: 10 Hz
        self.mqtt.configureConnectDisconnectTimeout(10)  # 10 sec
        self.mqtt.configureMQTTOperationTimeout(5)  # 5 sec

        return self.mqtt.connect()


    def send(self, topic, data):
        message = {}
        message['message'] = data
        message['timestamp'] = datetime.datetime.utcnow().strftime('%Y-%m-%dT%H:%M:%SZ')
        message['hostname'] = self.hostname
        messageJson = json.dumps(message)

        try:
            publish = self.mqtt.publish(topic, messageJson, 0)
        except Exception as e:
            self.log.error(e)
            print(e)

我关闭了wlan接口5个小时，然后又将其重新打开以使队列清空，以10Hz的频率清空队列大约需要12个小时。安全到多高才能更快地排水？我很困惑为什么要花这么长时间排掉队列。
