Comment 2 for bug 1445684

Affected versions:
6.0 Release; 6.1 build 309 also tested and have the same behavior.

Steps to reproduce:

1. Deploy openstack cluster using ubuntu+ha+vlan+neutron on cluster. Assumed that there will be at least one 10Gb NIC per compute for tenant networks.
2. Start two VMs on different computes.
3. Add required rules to the security group. Allow all tcp/(optionally udp if udp also needed to be tested) traffic in tenant or go with specific tcp/udp ports (5000,5001)
3. Run iperf -s on one of them and iperf -c <IP of first VM> on the second one.

Observed behavior:
Speed will be around 4-4.5Gbit per second.

Expected behavior:
Sales team would like to see 90-95% of wire speed here.
