I have very large BTreeFolder2 (CMFMember via BaseBTreeFolder in Archetypes)
- has about 260k items in _tree - objectIds() is painfully slow, as is
self._tree.keys() - I've casually observed using the meta type index to get
the object ids is many orders of magnitude faster.
Hacking objectIds() as follows (diff against trunk pasted inline) - gettting
ids off of the meta type index for all used meta types - seems to make
things much quicker. Two questions:
1. Can this be considered safe in all cases (I'll code this behavior on a
Subclass or in a monkey patch)?
2. If yes to #1, is there an appropriate place to lobby for this to be
changed, perhaps in BTreeFolder2 product itself?
