You are right. I've also got that permission turned off to take advantage of that part of the CMF workflow, which compounds the problem since it's site wide. I'm building the individual DateIndexs now and when that's done, I'll check the performance (for my own edification if nothing else 8-). Then I'll add that DateRange index and patch the CMF and check again.
Do you guys want metrics? If so, preferred tool/output method? (although my guess is, you already know how spiffy this makes things 8-)

Zopistas,
My ZCatalog is fast as admin, but dog slow as anonymous and other users. Anyone had this same experience? Details:
marjors:
Zope 2.6.2 CMF 1.3 Plone 1.0.5
about 50,000 cataloged objects (dual xenon server, plenty of ram, RAID)
User folder has 15k users in it, but admin is one of those users.
i've factored it way down and a simple search with just 1 Event loaded, like:
return context.portal_catalog(Type='Event')
is instantaneous for the 'admin' user, but takes about 10 seconds to return 1 SINGLE object. (only 1 Event loaded) imagine the time it takes to search and display 1300 events (which is what's normally in there). ouch. i've rebuilt the indexes, and still no dice.
Any help would be greatly appreciated.
This symptom probably has to do with the login in the CMF catalog which filters results based on the effective - expiration dates, for anybody without the "View inactive content" permission. I would guess that your portal_catalog is *not* using a DateRangeIndex to filter such content, but is still using the individual 'effective' and 'expires' indexes.
To fix this:
- Add a DateRangeIndex, 'effectiveRange', to your portal_catalog; set its start attribute to 'effective' and its stop attribute to 'expires'.
- Patch CMFCore/CatalogTool.py using the attached patch file (made against the released 1.3 version).
