archetypes.schematuning 1.2

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 they’re accessed. Factoring a schema is usually fast but in an average Plone Site, the ATDocument’s schema, for example, is accessed about 80 times per request. So caching it still makes sense, even if a single call is fast. With schematuning, ATDocument in PythonProfiler (which linearly slows down whole Python) came down from 1.518s down to 0.084s for Schema calls. This makes it roughly 18 times faster.

History

Roché Compaan and Hedley Roos 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.
