Is that an assumption, or measurement?.... there are several useful pages in control panel.
After restart + 1 minutes (1-2 accesses that does 1-2 catalog queries each) it's at 9,870 objects (total) using 130 MB of RAM, giving 13.1 kB per object. I've got profiling and debugging on now. From experience, it's varied from 8 kB to 13 kB per object. Okay, so what are these objects: CONTROL PANEL / DEBUGGING PAGE Top Refcounts: DateTime.DateTime.DateTime: 59530 BTrees._IIBTree.IISet: 4002 BTrees._IOBTree.IOBucket: 2573 RestrictedPython.compiler_2_1.misc.Set: 2308 AccessControl.User.User: 1632 Products.CMFCore.MemberDataTool.MemberData: 1628 BTrees.OOBTree.OOBucket: 1469 Persistence.PersistenceMapping: 1331 [...] OFS.Image.Image: 692 [...] App.ImageFile.ImageFile: 319 [...] The Cache Detail page corresponds to the Top Refcounts, but doesn't list many classes, such as DateTime.DateTime.DateTime? Hm, that's about all I can find out. Does this look strange? The application running on the site, by the way, is a BBS-type application with a few thousand messages imported from another system.
