And scalable horizontally, so… Hi Julien, Can you give some reference to Gnocchi's performance measurements? I have seen you presentation from the last Summit [1] but I cannot find information about Gnocchi's write throughput. In the issues slide you note the slow post API. The API responsiveness test shows that the API can handle correctly up to 2500 instances. You collect around 60 metrics per instance and use polling interval of 10 minutes. That would translate to: 2500 instances * 60 metrics/instance / 600 s = 250 metrics/s Are these assumptions correct?
