Hi, You can't exactly "turn off undo". This is a feature of the FileSystem storage. Even if undo were removed, the FileSystem storage works by appending all changes to the end of the file, so it would keep growing and growing. There are a couple of solutions. One: you can use BerkeleyStorage instead of FileSystem Storage. That storage (available on Zope.org) doesn't support undo, and also doesn't grow wildly when changes are made to objects. Two: you can store all of your poll results in an SQL database. For future development, I'd also recommend looking at ZPatterns... with that, you'll be able to implement some things in ZODB and others in SQL and have it all be pretty transparent to applications.

I'm having some problems with undo level, due to a poll flood, my Data.fs file have grown from 2MB to 150MB which turns Zope to a turtle (too slow), I already packed Data.fs, but I want to prevent this from happening. So I need to turn off undo, so Data.fs won't grow anymore. Does anybody knows how can I do this?
