While this is still experimental (py2.3 is not officially supported yet),
you're definitely right:

Python2.3 / +psyco
------------------
[std] 1st fetch : 4.89 / 3.57
[std] 2nd fetch : 0.73 / 0.64

Python2.3 -O / +psyco
---------------------
[std] 1st fetch : 4.65 / 3.55
[std] 2nd fetch : 0.72 / 0.64

No, I don't use this, thanks for the tip.

I'll check that however.
