Nadya, Julien,
We are working around profiling system based on logs. This will allows us to detect bottlenecks. We should make a couple of small patches in each project to support profiling. As we are going to be well integrated with OpenStack infrastructure we are going to use Ceilometer as a log collector. And we already made patch for this in Ceilometer: https://review.openstack.org/#/c/60262/ So it will be nice to get it reviewed/merged. Thanks.
