Hi, Folks, When we configure VXLAN range [1,16M], neutron-server service costs long time and cpu rate is very high(100%) when initiation. One test base on postgresql has been verified: more than 1h when VXLAN range is [1, 1M]. So, any good solution about this performance issue? Thanks, Xurong Yang -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-dev/attachments/20140529/3f70a993/attachment.html>
