Hi All, I just noticed that the undo tab on our zopeserver takes ages to load. If I try to trace the zope proces (as far as possible), it looks asif the entire Data.fs is scanned. Does zope scan the entire ZODB for old versions? It slows down our server enourmously with a 3G Data.fs. If so, aren't there more efficient ways to do this (backreferences to old versions for example) Ivo -- Drs.
