Hi there,
while working on my RDBMS storage for Archetypes we came across the fact
that content creation using "zopectl run" + the following script
for i in range(0, 10):
somefolder.invokeFactory('Document', id=str(i)
transaction.commit()
is about 4-5 times slower using at.schemaextender compared to a stock
Plone installation. This is even true for the case where we were using
the following document extender basically doing nothing:
class DocumentExtender(object):
adapts(IATDocument)
implements(ISchemaModifier)
own_fields = ('text',)
def __init__(self, context):
self.context = context
def fiddle(self, schema):
return
A profile reveals some insane high number (20k to 60k) of repetitve
calls (addField, checkPropertyDupe, visitImplements etc.). Is there
something broken-by-design in at.schemaextender or still space for
optimizations? At least with the current situation using
archetypes.schemaextender is appearently a NO-GO for larger Plone sites.
Thoughts?
