[PERFORM] Perl/DBI vs Native

Hi,

I have ran quite a few tests comparing how long a query takes to execute from Perl/DBI as compared to psql/pqlib. No matter how many times I run the test the results were always the same.

I run a SELECT all on a fairly big table and enabled the log_min_duration_statement option. With psql postgres consistently logs half a second while the exact same query executed with Perl/DBI takes again consistently 2 seconds.

If I were timing the applications I would have been too much surprised by these results, obviously, processing with Perl would be slower than a native application. But it's the postmaster that gives these results. Could it be because the DBI module is slower at assimilating the data?

Any light on the subject would be greatly appreciated.

Regards,

Val
