- DO NOT use getObject to then just get an UID. It is ready to use in SQL result. This saves a roundtrip to ZODB (which can be in a remote ZEO server).
- DO NOT use getXXXUid() to then feed the uid to catalog to get the real object. Uid _has_ been fetched from the actual object in the accessor anyway. So just grab actual objects, and fetch uids from them when needed. This saves a roundtrip (...per iteration !) to catalog.
- Use "IN" instead of "OR" with equality in SQL query (minor improvement compared to the 2 above)
