Open Stack

Hi list,

I'm doing some tests on Openstack, and notice that security group has really worse performance impacts.
But, I'm not really sure how much performance drop is caused by security group.
So, I want to do a compare test with case 1: security group enabled and case 2: security group disabled.

Can I disable security group in Openstack ???

Is this configuration for nova correct ???
/etc/nova/nova.conf
#security_group_api=neutron
firewall_driver = nova.virt.firewall.NoopFirewallDriver

Thanks.
