A more aggressive opaquespeedup package to improve performance by Makina Corpus
This path improve overall performance of Plone. It remove opaqueitems feature from CMF (just keep talkback support)
The result is 25% better on the total time spend in the request. Becarefull if you use a third part product that use opaqueitems and make me know if you it is, I will add it to this page. At the moment only talkback use it and are supported.
