Michael, you nailed it again. My libpq test C program delivered
between 2400 QPS and 5000 QPS vs ~10 QPS for DBI/DBD::Pg on this
box.
It remains unclear to me why the same DBI/DBD::Pg client code
would deliver performance 2-3 orders of magnitude better on
other roughly comparable or inferior boxes.
What would be the recommended replacement for DBI/DBD::Pg as a
perl interface?
Thanks,
Ed
