PH61346: After PH50302 et al, compile performance improved for some programs but got worse for others

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An earlier improvement to compile times for programs with a
  large number of repetitive paragraph PERFORMS unintentionally
  caused the compile times for some other programs to get much
  worse.
  

Local fix

• Compile at OPT(0)
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.3 compiling      *
  *                 programs with OPT(1|2) that contain a large  *
  *                 number PERFORM statements.                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: Program takes an excessive time to      *
  *                      compile                                 *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF                       *
  ****************************************************************
  When compiling a program that contains a large number PERFORM
  statements, some analysis done by the optimizer may take a long
  time to complete.
  

Problem conclusion

• The compiler was fixed to tune that analysis when a program
  contains a large number PERFORM statements.
  

Temporary fix
