Hi all, Currently, openstack heavily uses iptables in network setup(firewall, NAT, etc.), which may trigger performance issue on some situations. For example, I have ever found packet dropping in host for several times, due to connection tracking triggered by NAT.
By now, I have to find some stuff on the internet to do performance tuning for iptables. Is it a correct direction to go, or is there any mature solution for this issue? Best Regards. Yufang
