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
