我的一项服务运行不佳，但是当添加新消息的速度下降时，该服务从Amazon SQS检索消息的速度会大大提高。
Period A:
Around **25 000** messages per minute are being added to the queue.
The rate at which the service collects messages is around **18 000** messages per minute.
Period B:
Around **10 000** messages per minute are being added to the queue.
The at which the service collects messages is around **35 000** thousand messages per minute.
大量消息进入队列是否会使从队列接收消息的速度变慢？我试图浏览文档等，但找不到任何东西。
感谢您的帮助！
