Joe, There are a number of problem reports on ceilometer performance and some promising blueprints to address them. I'd suggest we re-run the performance test when those are in place. Having reference performance tests such as this are helpful to pick up cases where there are regression or sca

Hi Ilya, Interresting, thanks for sharing. So the quick conclusion to your numbers seems indicated that mongodb is more efficient for both reading and writing, except for 2 cases for retrieving data (meters and resouces listing) .. However for the reading operations, it's should be confirmed (or

2014-04-21 Thread Ilya Tyaptin
Hi team! In light of discussions about ceilometer backends, we decided to test performance of different storage backends with collector and api services because these services depend on backends availability. For the collector testing we are using not completely real data, we are generating looki
