To summarize it: while analying performance of the Plone 3 codebase they noticed a lot of time was spent trying to figure out which types could be added at a location. Part of that logic uses the TypesTool _queryFactoryMethod function, which goes through the dispatcher to get to the factory method for a type, which is apparently very slow in Zope 2.10, and much faster in Zope 2.9. Any idea why the code is different between 2.9 and 2.10? Rocky modified it in changeset 67869 to be able to support external methods outside of products. The problem with the new code is that it imports all products to figure out some of their details. So for every factory dispatcher access we now have an import for each product, which means lots of filesystem accesses and python interpreter work being done. They came up with http://paste.plone.org/13211 which is an imho somewhat evil approach which introduces a thread-local cache for App.FactoryDispatcher._product_packages. As described below the speedup as a result of that is huge. I would not be opposed against such a speedup patch as long as it does not raise other problems. However I don't know App.* enough to be evaluate the patch. http://paste.plone.org/13217 should do the trick. It makes _product_packages cache its result using the list of products in Control_Panel as a cache key. That makes sure that removing or adding products there will not result in stale data being returned by the dispatcher.
