Has anybody else found that the ruby dbi + pg_dbd performance to be slow?

I'm running a unit test that selects all the records in a single
PostgreSQL table. I'm finding that the select of about 300 records
takes about 0.2sec using the direct ruby postgres binding while the
DBI takes anywhere from 2.8-6 seconds.
