[Zope] Zope using DB

[Jorge O. Martinez]

Hi:

I too was curious about this subject, and found a couple of links that 
can shed some light hopefully (I think one for them from Matthew):


http://aspn.activestate.com/ASPN/Mail/Message/zope-Dev/1006799

http://www.zope.org/Products/OracleStorage/OracleStorageFAQ.html


The real question is...anyone out there with a real world app can share 
some real performance data...? Is it worth the while going to an 
OracleStorage solution...or not?

Regards,

Jorge M.
