  ****************************************************************
  Initial response times from web applications are slow.  The
  problem is most visible when large applications are deployed
  containing large numbers of libraries.
  Applications making use of Spring, Hibernate and Struts2
  technologies will be particularly prone to slow initial
  response times.
  

Problem conclusion

• A number of improvements were made to remove unnecessary code
  paths and to optimise resource lookups and path normalisations
  with the introduction of a caching mechanism.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.0.2. Please refer to the Recommended Updates page
