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.
