This is a dprofpp -I result. It means that it displays subroutine times 
inclusive of child subroutine times. I suppose for example that 
C4::Context::new call C4::Context::read_config_file that call 
XML::Simple::XMLin. So we know that globally 16.7% of response time is 
spent reading config file. If, thanks to mod_perl, a

So reading config file may be not so slow but it is called 23 times! If 
you add a warning in this procedure, you see it is called from those 
modules:

   1. Context.pm
   2. Output.pm
   3. Languages.pm
   4. Auth.pm
   5. Members.pm
   6. Dates.pm
   7. Log.pm
   8. Circulation.pm
   9. Stats.pm
  10. Reserves.pm
  11. Biblio.pm
  12. Koha.pm
  13. Branch.pm
  14. ClassSource.pm
  15. ClassSortRoutine.pm
  16. Heading.pm
  17. Search.pm
  18. XSLT.pm
  19. Items.pm
  20. Accounts.pm
  21. Overdues.pm
  22. VirtualShelves.pm
  23. Tags.pm

23 calls! It has to be fixed.

marcxml biblio records? Even on a setup without XSLT?
