Java RabbitMQ接收速度慢

我需要创建一个应用程序，它应该从数据生产者那里接收数据并进行处理。我选择RabbitMQ作为消息代理。我的测试结果显示不是最好的：

发送-100 msg
生产-100味精/秒
消耗-6味精/秒

为了解决这个问题，我设置了listenerContainer.setAcknowledgeMode（AcknowledgeMode.NONE） 但我需要一些排队的人。我不能用worker并行处理，因为消息的顺序对于数据处理很重要

有可能提高接收速度吗

在具有2个vCPU和4 Gb内存的实例上进行了测试。

您可以增加容器的

预取计数，这将大大提高性能。但是，如果拒绝并重新获取消息，则将丢失排序（重新获取的消息将位于预取消息的后面）
