Hi,all!
I test MQ performance on different platform. I use MQ's sample application "amqsputc", and put messages through CHANNEL. I setup MQ server by default.
--**SERVER**
2 XEON(hyper-thread) CPUs, 2G MEM, 3 disks. OS Radhat 8.0
I find it can put about 110 persistence messages per second.
--**PC**--
P4 2.4G, 512M MEM, 1 disk. OS Redhat 8.0
It can put about 1000 persistence messages per second!
That is, PC is 10 times faster than SERVER! Who can tell me why? |

I assume, that you used nonpersistent messages in the second test, it's about ten times faster.
This comply with my own tests. The perforemance of persistent messages are more depend on IO than CPU.
amqsputc works with MQPER_PERSISTENCE_AS_Q_DEF. |

| I'm sure that I used persistent messages in the all tests! |

Two things:
1. Are there any other heavy tasks running on the server?
2. What do you mean by

?
I guess the best way to do this test would be to modify amqsputc so that MQPUT and MQCMIT are executed many times in a loop. If you use a channel to deliver messages to the QM, you count network delay into your result (are these two machines available within the same LAN)?
