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.

    New caching mechanisms were added to improve ClearQuest Unix
    performance.
