fastest postgresql module

[Timothy Smith]

has anyone got some hard numbers on which pg access module is the 
fastest, i currently use pypgsql, but i can't help but feel it's a 
little slow.
3 seconds to connect, send one query, get th return data.
i'm on a adsl 1.5mbit/256kbit link, the server is on a 10/10mbit, and i 
have a ping of 245ms average.
maybe pypgsql does too much backand forth, i don't know.
