Certainly peak usage would be 1:1. But that still allows for lots of distributions - e.g. 1:1 2% of the time, 10:9 80%, 10:7 95% vs 1:1 90%, etc. Some of the devs on this list also run clouds, so I'm curious if there are data available indicating what kind of distribution of this ratio they see in practice. _______________________________________________ OpenStack-dev mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
