I m currently profiling the code of Plone to find performance issue and
fix them (i m sure there are a lot).
There are things I don't understand very well, so sorry if I m wrong.
The code of CMFCatalogAware.opaqueItems parse every attributes of
plonesite and evaluate this for each attribute:
isImplementedBy calls takes 30% of the time spent.
But z2ICallableOpaqueItem is a Zope2 interface and I m not used to this
kind of object. It seems they are generated on runtime, so for me it's
hard to debug.
My questions are:
* What are opaqueitems (any example ? I don't have find anything usefull
in tests of CMFCore)
* Is zope2 interface are still used and why ?
* How could I replace those calls, or improved this code that always
return an empty tuple
PS: sorry for cross posting if there are because i have some issues with my
other email address.
