| Regardless of all of the potential hypothetical situations, the thing that needs to be debugged first is the channel. |

I'm sticking with 
Because the channel is:
- the cause
- a symptom
- an innocent bystander (or Millicent Bystander)

maxdepth : 10000000
average message size : < 1 MB
df - k -> Receiving system is have enough space. Since only one folder occupied with 15 % of the space.
All,
Could you please tell me which parameter I have to concentrate on the perfomance improvment for the channels.
I have one query against this thead.
1) Will we have concept of thread for the sender or receiver channels ? Since I could not find exact answer in the Infocenter. |

What is the status of the channel?
If you stop the channel, and display qstatus on the xmitq, does it show uncommitted messages? |

What do you mean by slow? You say you are sending 150 mps from Q1 an Q2 to G1 (G1 is receiving 300 mps)
How do you measure the time to transmit messages takes? 1.000.000 messages , one hour?

Does the rcvr channel go into paused or retry state? Even briefly?

No.. Both the sender and Receiver channels are running. Once I load 50000 messages and start the sender channels.

It is sending 150 mps rate. Average Message size is 15 KB.
Any option for the performance tunning ??
Or
Is there any concept of thread for the sender/Receiver channels ? |

The channel status is running when messages are flow between transmission to local queue of other QM.

For the above scenorio, the uncommitted message count is zero. |

What are batchsize and batchinterval values at both sender and receiver channels?
Are both boxes similarly provisioned? CPUs? Ram? Disk space?

Batch size is 50 and Batch interval is 0.
Both the systems are configured for the performance test. CPU utilization is below 10 percentage when we do the perfoamance test.

I could not find any log information for the message transferring between the remote and local queue of other QM.
If any log file will be there for message transfering , Could you please tell me the default log file location. |

The InfoCenter will contain a complete description of the file system for your o/s. look for AMQERR01.LOG.

There is only the MQ error logs. They would make mention of issues occurring with the channels. |

Picking up where Vitor left off....
You can't store "billions of messages" with this queue, or any MQ queue.

And depending on message persistency, your logging type and logging space you might run out of logging space before you run out of queue space...
