"it depends", unless you have a lot of experience with it, Zope and CMF, you might well find yourself with a slow site on your hands and not many apparent options ;-) I'm using CMFMember also-why is it 'apalling'? It's an incredibly heavyweight and inefficient solution to a problem that requires an extremely fast and efficient solution: user object are used a LOT in most Zope apps, CMFMember makes them slow, in a numbner of ways. Generating writes which result in AT-based member objects being reindexed and often resulting in conflicterrors that dramatically slow down a site is not a good thing... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Hi Dieter, Dieter Maurer wrote: I am setting up sites using Plone and am concerned to read some of the comments on it. Is it really that bad performance wise? No, it is not. ...I agree, if it is correctly set up and optimised, which isn't the case if someone is here complaining about performance, which sadly, new users blown away by Plone's functionality often are... It is just that the CMF is unable to fix a year long bug which affects Windows only when Zope is run in debug mode: then each access to a "filesystem directory view" triggers a hierarchical file system scan. The result is a slowdown by several orders of magnitude. FWIW, my experiences with Plone are predominantly on Linux, and that's what my comments are based on... The problem disappears when you either: * turn off "debug mode" Yes, this is a biggie. Thankfully, I believe newer versions of Zope ship with this turned off by default? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

The problem disappears when you either: * do not run on Windows * turn off "debug mode" * fix the silly bug Of course, a Plone site is not as fast as a static one.
