阿里云物联网服务端订阅问题

问题描述

我在开发阿里云物联网的服务端订阅功能，听阿里云的工作人员只能通过/topic/#，来获取获取所有的设备发送的信息，如果我有几千台设备同时发送信息，同时都到这一个接口来区分和保存信息会不会并发很严重，请问大佬们有什么解决办法吗，现在服务器是16核的，我该如何优化我的代码呢？

        $clientId = $this->uuid();
        //iotInstanceId：实例ID。
        $iotInstanceId = config('api.iot.iot_id');
        $timeStamp = round(microtime(true) * 1000);
        //签名方法：支持hmacmd5，hmacsha1和hmacsha256。
        $signMethod = "hmacsha1";
        //userName组装方法，请参见AMQP客户端接入说明文档。
        //若使用二进制传输，则userName需要添加encode=base64参数，服务端会将消息体base64编码后再推送。具体添加方法请参见下一章节“二进制消息体说明”。
