When I have the program connect to the DB via ODBC, performance is significantly slower compared to when I have it connect via libpq. I was able to achieve ~1000 transactions per second using libpq, but only ~4 transactions per second using the ODBC driver.
I'd suggest setting log_min_duration_statement = 0 in the server's
config file. Then repeat the test and look at the log file to see where
the time is spent. If that gives no clue, I'm happy to take a look, if
you can reproduce it with a small test program and post it to a list.
