OK, yea, it's not real clear where configuration preference go (i.e.
system.properties or tomee.xml). My goal is to have 100 messages processing
simultaneously for each MDB. I could have 5 or 10 distinct beans that need
to handle up to 100 messages each simultaneously. In case of 10 beans with
100 simultaneously messages (1000 total) would I have to use:

Default\ JMS\ Resource\ Adapter.ThreadPoolSize=1000
Default\ MDB\ Container.InstanceLimit=1000

Is there any implications to this? I have a scenario where I could have a
onMessage last up to 30 seconds and we have tens of thousands of users. I
need it to scale to a lot of MDBs. Are there OS tuning considerations based
on the number of active threads?
