i'm not aware of how universal installer configures plone, but from what you shown i can conclude that you only run one zope instance. you should have as many zope instances as many cpu's (cores) you want to be used. and they all must poit to the same db backend (zeo). infornt you should put somehting like pound to balanse the load. maybe even simple load balanser from nginx would be ok for start. -- Rok Garbas http://sharbas.blogspot.com/ _______________________________________________ Setup mailing list [email protected] http://lists.plone.org/mailman/listinfo/setup
