replying to myself:
i now do a ZopeFind (or correct: two nested ZopeFinds) in the External
Method (attached) and give the result to the converter function. It
works now reasonably fast, even with all my ZClass instances (about 600).
Is there so much overhead in Python Scripts calling an External method?
(i used also ZopeFind in the PythonScript, in a variation of my previous
mail)
Or is it the getObject() call in the Python Scripts?
Ciao,
Jochen
