Subject [jira] [Commented] (AMQ-5379) AMQP - allow setting prefetch size
Date Tue, 14 Oct 2014 16:35:35 GMT

    [ https://issues.apache.org/jira/browse/AMQ-5379?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14171186#comment-14171186

Robbie Gemmell commented on AMQ-5379:
-------------------------------------

I just came across the update on http://activemq.apache.org/amqp.html which notes regarding
the prefetch config toggle "that the same value will be used for broker-side amqp receiver
link that handles incoming messages". This is probably going to lead to people accidently
reducing the producer credit window to smaller values, which will then hammer producer performance,
since even the default value of 100 is likely to be limiting in certain cases already. I would
suggest adding a seperate config toggle to alter the credit window for producers independently
from the vaue used for consumers.
