[Zope] Data Insert Problems

[Jay Zeemer]

Chris,
OpenSTA is an open source load testing tool (http://www.opensta.org/).  We
are trying to see if we can use Zope as a replacement for a heavily
application. We need to to handle a sizable amount of through put, and have
not had much success so far.  I dont believe we are writing to the session
object, been trying to avoid using session objects because we plan to load
balance our solution.  Please take a look I attched the processForm source,
any and all recommendations are appreciated!!

Thanks
Jay

Can you show us the code for processForm?

I wonder if you're using the session object? writing to that can cause 
conflict errors as it is a mounted zodb storage...

cheers,

Chris
