I'm pretty sure this works.

Ok, I get it now. I misread it the first time.

This returns the equivalent of running self.objectIds(spec=self._mt_index.keys()) on the current trunk/release code, which should be identical to self._tree.keys(), but much, much faster. I'm still somewhat ignorant as to why self._tree.keys() is so slow with 100k-plus objects (waking up too many persistent objects?),

I suspect the cost is in creating ghosts for all of the persistent objects.

No objections here--I like this patch.

Thanks Shane - glad it makes sense. I don't have contributor rights - would you or anyone else be willing to gateway this diff for me and commit such changes? Thanks, Sean
