Setting the queue size of VM queues

Hi

We are using mule 1.4.3 for system where it is handling very high load. (eg: around 80 TPS). Some time we have observed that few mule components getting delayed. So by looking at the logs we have identified exact point where the delay has introduced.

We are using MuleClient to send the messages to VM queues. Within the very high traffic time, this process get delayed hence the whole system performance get reduced. So the message sending to VM queue takes longer time than the low traffic time.

I'm wonder whether is there anyway to increase the queue size of the VM queues.

I have found the same in the forum: http://www.nabble.com/Re%3A-How-can-I-set-the-queue-size-of-VM-transport-p14164824.html

and the configuration details can be find out in : http://www.mulesource.org/display/MULEUSER/Configuration+Options

By increasing the "queueProfile" to 2000 will this issues get solved?

Please advice?

Thanks in advanced,
Thilina
