    Re performance metrics:
    it is a work in progress, but I've built something to provide real time instrumentation on the journal performances: https://github.com/franz1981/activemq-artemis/tree/real_time_journal_latency
    
    Right now I need to:
    - define a better lifecycle of the instrumentation -
    - add a console command that collect the samples using the IPC [RCU](https://lwn.net/Articles/262464/) buffer I've built, translating them in a human readable form
    
    The cool thing is that it could be enabled in production system too with no performance impact.
