Hi,

I assume you are referring to asynchronous consumers. You
can reduce the size of the message backlog for asynch consumers
by configuring a customer connection factory for the consumers
and lowering the "MessagesMaximum" value on the factory
from its default of 10.

If you are using MDBs, there are further tuning options. For
more information, refer to the JMS Performance Guide white-paper
linked from here:
