archetypes.schematuning 1.1

More Speed with cached Archetypes Schemas.

This package speeds up Archetypes Schemas and is a patch for Products.Archetypes.

It uses plone.memoize to cache Archetypes Schemas instead of factoring and modifying them every time its accessed. Factoring a schema is usally fast anyway. I.e. in an average Plone Site a, ATDocuemnts schema is accessed per request 80 times. So caching it makes sense anyway, even if a single call is fast. With schematuning ATDocument in PythonProfiler (which linear slows down whole Python) came down from 1.518s down to 0.084s for Schema calls. This makes it roughly 18 times faster.

History

Roche Compaan and Hedley Ross found while working on one if their projects several performance issues. One of it was the often repeated BaseObject.Schema() method. Read about it on the Mailing-List.
