Subject Re: Re: What is the effect of dedicatedTaskRunner Attribute?
Date Wed, 12 Feb 2014 07:32:17 GMT
Hey,

So If I use this configuration : *"optimizedDispatch=true" and
"org.apache.activemq.UseDedicatedTaskRunner=true"   
*
 
It means the sending thread will do dispatch, (There will not be a separate
thread for dispatch) and it will not use ActiveMQ thread pool (since I have
enabled dedicated task runner which is also in default configuration). 

AND

I am not able to find the thread name for dispatch and send. I have attached
my thread trace here which is pasted below:

I have tested by disabling dedicated task runner in my setup but not found
any thread reduction.
Can you tell me which threads (THREAD NAME) are going to reduce in below
thread trace if I disable dedicatedTaskRunner ?
