Regarding this, I was wondering what kind of impact it has.  If I have 5 child process, queue interval at 5, I almost never get more than 3 messages in a batch.  Is it better to run less childs or have them look in the queue less often to be easier on ressources.  I guess the first saves memory and the second saves cpu? 

Thanks,
