You didn't mention where you were storing the metrics. If you store them in the same MySQL DB that's used by Nova for example, it's likely that's the problem is the load Ceilometer puts on the MySQL cluster slows Nova down. I don't think it's worth running the test with more instances for now. The results are clear, the next action should be to see why things are slowed down that much. It shouldn't happen. -- Julien Danjou # Free Software hacker # independent consultant # http://julien.danjou.info
