Hello, We have a script that does a'database import' into the ZODB. This script iterates through a series of records (currently in text files) and creates corresponding Zope objects. We can do small (<100) imports relatively well, but on a large import (1000+) the Zope process balloons in size and eventually becomes unresponsive. Sending a SIGHUP to Zope restores normal functionality and performance, and the created objects all seem to work fine. However, we don't want to have to restart Zope every time we do an import. My suspicion, based on the above evidence, is that the ZODB caching mechanism is to blame for the slowdown. Can anybody confirm this, or offer an alternate explanation? And, if caching is the culprit, is there a way to programmatically turn off caching for the duration of a script run? Thanks, VanL
