MQSeries.net :: View topic - Performance, Scalability Issue ? in non clustered env.

Here's the background on the environment before I ask for advise on the issue.

Background: We have a non clustered MQ environment and each server hosts one and only one Queue Manager and owns approx. 50 queues. All these queues are enabled for message persistence. The TCP connection to a queue manager is established using "inetd" daemon. The throughput for one Queue Manager in a day is approx. 5 million messages and is growing. And there are three queue's that are high volume and they contribute to 70% of the Queue Manager's total throughput per day. And the system activity on this machine is normal for example peak CPU is under 40% during peak traffic.

Issue: One of the high volume queues receives a total of approx. 2 million messages per day. Typically these messages arrive at a rate of 20K in 30 mins however sometimes we receive it at a faster rate i.e. 150K messages in 30 mins. And the messages are held in the queue for a few hours (6+ hours) before the consuming application completely de-queues it. While the application can be made to de-queue faster we can't do that because of downstream applications and infrastructure limitations.

So the question is: Does this queue holding so many messages approx. 500K messages at a time present any potential problems with regards to performance, scalability or availability ?
Thanks !
