Hi Steve, I ran it against 11.2 multiple times and cannot reproduce the behavior you describe. I see following consistent results: plsql_code_type = interpreted => 3.21 secs plsql_code_type = native => 2.9 secs (nr of iterations set to 10000) To be able to test this I had to add a missing table db_error_stack_context which is referenced type declarations in msc$log_p (e.g. SUBTYPE stSource IS db_error_stack_context.context_at%TYPE): create table db_error_stack_context (context_at varchar2(1024) ,context_value varchar2(1024) ,context_name varchar2(1024) ); Regards, Andre -----Oorspronkelijk bericht----- Van: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] Namens Steve Baldwin Verzonden: vrijdag 25 december 2009 21:34 Aan: Jared Still CC: oracle-l@xxxxxxxxxxxxx Onderwerp: Re: Native compiled code *much* slower?? Here's the same but with attachments to make things (hopefully) a bit easier for folks to see if they see the same behaviour. Cheers, Steve
