Hi,

Normally, as a safety precaution, MQ fires off a process called AMQZLAA0 - rhis is your interface to MQ. This slows things down a bit, so to speed things up, you can use CONNX which will correct you direct to the queue manager, without the intermediate process.

Two drawbacks:

1) Only users in the MQM group are allowed to use this feature - and you don't want to go around putting people in this group all the time;
2) This has the POTENTIAL of screwing things up a treat if your application program misbehaves. It COULD corrupt the MQ shared memory and other IPC stuff.

HTH!
