-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In current Zope2 (ZODB <= 3.7.2), the OFS.Image.File object's 'index_html' shows particularly obnoxious tendency to destroy locality of reference in the connection cache. I wrote the problem up as a Launchpad bug:
https://bugs.launchpad.net/zope2/+bug/157245 That bug report also sketches a solution: I have checked in an initial stab at implementing it on a branch in SVN: http://svn.zope.org/Sandbox/tseaver/no_pdata_in_cache_dammit/ Thoughts? I realize that a not-yet-released Zope2 which uses the ZODB 3.8 blob storage stuff might not have this problem (assuming that OFS.Image.File is updated to take advantage of blobs). Also, as I note in the issue, the fix doesn't help the thrashing of the disk-based cache used by ZEO client connections.
