That's a bad argument. Several projects only use zope.interface and its 
adapter registry (for example twisted). For them a 20-26% improvement for the 
adapter lookup would be significant. Just because other parts of Zope 3 are 
even slower and use more time than the adapter lookup, it does not have to 
mean that this is a bad/insufficient improvement.
