In this case, it may be due to the "set isolation level" issued together with the "begin" by psycopg. Because you send a very short statement between BEGIN/COMMIT pair the code for the set could be a relevant part of the communication. The overhead would be less relevant with bigger commands per transaction of course. This is a point I just wanted to talk about on the ML: will try to write this evening/in the next few days. -- Daniele
