MQSeries.net :: View topic - Very poor performance of put operation with MQ V5.3

Hello,

I have an environment where the put message performance is very poor. My environment:
pSeries 630, 4 CPU, 8GB RAM
AIX 5.1 ML5 64-bit kernel
MQSeries 5.3 ML7
J2RE 1.4.1 IBM AIX build ca1411-20030930

The problem is that when I put a large text message on a queue with a java client, the put process takes around 8 seconds for 1MB message. Strage thing is that if I use the java libraries (com.ibm.mq.jar) from the previous instalation (MQ V5.0) the put operation takes 500 miliseconds. My queues are not persistent, and I am not using JMS APIs to put the messages.

Any ideeas? Is there something completely wrong with my configuration?

Regards,
Horia
