I don't know if that's related, but I had cases where an empty index (all cataloged items removed, all lexicons or vocabularies removed) still had a size of around 6 MB (when exported in *.zexp format). That means that some stuff is not deleted correctly.

Zope 2.5.1A "PathIndex" maps (pathsegment,level) onto the "IISet" of document ids with "pathsegment" at "level" in their path. An "IISet" is a single persistent object, written as a whole to the ZODB. Its size is proportional to the number of entries. Therefore a ZODB storage with undo support grows quadratically with respect to the number of entries (between packs). The standard "path" index indexes based on the physical path. Therefore, the size of the index entry of (at least) one of the top level pathsegments is in the order of all indexed objects. Once, you have lots of indexed objects you will observe significant ZODB growth between packs. The fix would be easy: "PathIndex" should use "IITreeSet" rather than "IISet" to store the document id lists (as do other indexes). (There are more bugs in "PathIndex": e.g. it does not remove old index information when a new "index_object" brings in new data. A code review would be appropriate.) A quick workaround: delete the "path" index unless you really need it.I am going to fix the problem for Zope 2.5, 2.6 and HEAD next week.
