If it is metadata agent load related: Are you caching the metadata info? (configure memcached_servers in nova.conf) We noticed a huge benefit on the metadata agent performance. Within our cloud the biggest load is created from facter (puppet) which will query the metadata agent. This adds up to quite a lot of requests to the metadata agent quickly. Adding caching significantly decreases the load on all systems. (Without caching we have a VERY high nova-conductor load) Cheers, Rober van Leeuwen _______________________________________________ OpenStack-operators mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
