Error description

  • The M2001 IBM MQ Appliance does not perform as expected when
    using HA functionality.
    
    Comparing the performance against a normally-performing M2000
    appliance shows that the M2001 appliance using the MQ 8.0.0.5
    firmware exhibits slower networking performance.
