So it makes a difference if you fetch *a lot* of data. Anyway, if you don't have a performance problem, you don't need to care ;-) Yes there is a way to try it out, install it and compare :-P As I said, there is a win32 version of psycopg if that's the only platform you have access to: Google - first hit: http://www.google.de/search?hl=de&q=psycopg+win32&btnG=Google-Suche&meta= => http://www.stickpeople.com/projects/python/psycopg/ -- Gerhard -- http://mail.python.org/mailman/listinfo/python-list

Re: fastest postgresql module
my only issue with psycopg, is last time i looked they had no win32 port? Not completely true. Since long time ago there is a website with unofficial psycopg binaries: http://www.stickpeople.com/projects/python/psycopg/ Regards, Josef -- http://mail.python.org/mailman/listinfo/python-list
Re: fastest postgresql module
With the round-trip time of 245ms, three seconds only allows for approximately 12 packet exchanges (roughly 24 total packets). I think latency is your problem. casevh -- http://mail.python.org/mailman/listinfo/python-list

It has one now. But (of course depending on your query), your issue is not dependant on the particular PostgreSQL, I think. You'll probably also have it with executing a plain vanilla script via psql. -- Gerhard signature.asc Description: Digital signature -- http://mail.python.org/mailman/listinfo/python-list
