Oh, right, that makes a huge difference!
First, I'd make sure to use the extensions,
then an analysis of the SQL statements
should be done to look for optimisation.
Both Aaron and I are happy with some contract work. :-)

Hmm, I appreciate that you want to use Stackless, but
I don't see how this could make your program faster.
The overall C stack fumbling is almost the same as in
regular Python, just that I do less recursions.
And if you application needs 30% speedup from Psyco,
you are still about to loose with just a bit more clients.
