I am after any information or issues that people might of experienced from having multiple production queue managers on one server. At present we have two queue managers on a HP-UX server and could be looking at adding an extra one.
Does anyone have ballpark figures as to how much memory and CPU a queue manager uses etc???? I know it is a very open question but any ideas will be appreciated.
Cheers
Pete |

In my experience with MQ/Unix, it seems that memory and CPU aren't main concern; it's actually I/O and resource management (semaphores, shared memory, spinlocks, etc.) because typically a modern Unix server will have at least a gig of RAM, and many times more than one processor. For instance, the greatest performance increase we saw on our AIX servers was when we implemented full-fiber disk I/O. Because we were dealing with syncpoint/persistent messages, everything needed to be written to disk. Our message throughput made huge gains once this bottleneck was eased thanks to the fiber connections...

Thanks Brandon, That was what I pretty much thought, I just needed confirmation from someone else.
