APAR status

• Closed as program error.

Error description

• Performance differences were noted between Solaris and Linux.
  Solaris appeared to load 1 record (GetEntity) slower in a basic
  CQ API test.
  
  The delay was due to the time required to load the schema, in
  particular the time to load the hooks, particularly on Solaris 9
  SPARC.
  
  The fix for this issue may improve performance for all
  UNIX/Linux platforms.

  schemas with many hooks.
  

Problem conclusion

  New caching mechanisms were added to improve ClearQuest Unix
  performance.
