The FDC is a text file , with a readable header. (127.0.0.1) (9494)' This message shows tcp port 9494 being used , but in you test you have port 1414. Why is this?
OK, just did some research and ... |

I tried you script in one box with MQ 7.5. Run five times and the result was
18; 18; 18; 18;19 secs.
Maybe the PROD environment has more work to do (other applications)?

What is the difference if you use the ping command from the OS to address the relevant hostnames (localhost, ip address, etc.)?
These are for the PROD server (bad performance):

There are sample applications shipped with MQ:
amqsput
amqsputc (client version)
they are very basic.
There are several supportpacks that can also be used. MO71 can be used.
