  USERS AFFECTED:
  All users of IBM Integration Bus on z/OS parsing MRM messages.
  
  
  Platforms affected:
  z/OS
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  IIB customers on z/OS migrating from WMB v7, with message flows
  that access MRM message trees, might see an increase in CPU
  usage in the nodes in which the MRM message tree is parsed.
  
  Users who parse multiple MRM messages inside a single flow
  invocation are more likely to observe the performance
  difference, especially if they utilise a different set of
  message
  sets on each parse or invocation.
  

Problem conclusion

• The product has been modified so that the performance costs of
  parsing an MRM message on z/OS are reduced.
