[Zope] Best performances setup ?

Hi, I recently discovered Zope, and a few questions came to my mind... - what is the best performance setup for Zope : is it better to use only a native ZServer or Apache with PCGI mode ? What are the benefits of each mode (security,...) ? - how many objects can the Zope database containt without any huge loss of performances ? Is there a file size limit for this database ?? Thank you for any advise... Thierry -- Les LOGICIELS LIBRES ?? Y'a moins bien, mais c'est plus cher !! http://gpc.sourceforge.net
