Hi

This is the question from mq sample test.

Queue managers QM1 and QM2 are connected. Two WebSphere MQ applications (APP1 and APP2) send messages from QM1 to QM2. Each application has ten remote queues defined on QM1, pointing to ten local queues on QM2. Each application has its own transmission queue, and its own channel defined from QM1 to QM2. Communications are over a 9600 bit/second line, using TCP/IP. Both applications are in constant use, and both channels are fully utilized. Which of the following changes will have the GREATEST benefit on channel performance? (One answer)

A. Decrease the batch size on the channel
B. Define more channels from QM1 to QM2
C. Define fewer channels from QM1 to QM2
D. Install a second line

Can any one explains me which one is correct and other stratagies if any.

Many thanks in Advance
Eswar.
