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!!

Hello all,

I am currently running into an issue with an application I am working. I have a form, currently 5 fields but will soon grow to be much larger, and when I run 50 conncurrent users against it from Open STA.

What's Open STA?

ZODB conflict error at

/VirtualHostBase/http/server.domain.com:80/VirtualHostRoot/dir1//dir2/submit

/processForm (27 conflicts since startup at 2005-03-21T13:33:44)

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 -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
