Basically you see the messages 1 by 1 from different instances,not that smooth.
Though these are processes running in a ubuntu, should be multi-threaded.
Is this expected to be so or it's just running slow ?
thanks !

I'm not sure what you mean by "see the messages 1 by 1", but each UML
instance runs as a separate Linux process (several "interwoven"
processes, actually), so multi-threading does not play any role here.
