[petsc-users] Petsc without debugging enabled

[Michele Rosso]

Hi,

I am performing some timing runs with PETSc. I think I correctly
compiled it with no debug mode, yet -log_summary gives me a warning:

      ##########################################################
      #                                                        #
      #                          WARNING!!!                    #
      #                                                        #
      #   This code was compiled with a debugging option,      #
      #   To get timing results run ./configure                #
      #   using --with-debugging=no, the performance will      #
      #   be generally two or three times faster.              #
      #                                                        #

Here are my configure options ( from -log_summary ):
