Hi Everybody, At the summit there was a session on Keystone Performance. The notes are here: https://etherpad.openstack.org/havana-keystone-performance My group is experiencing performance problems with our openstack installation that we would like to quantify- you can't fix it if you can't measure it. We have some suspicions that the issue is related to keystone (and our use of LDAP). Before we invest too much time into this I wanted to know if anyone else has done any profiling of keystone or any other openstack components. Some brainstorming ideas we had when considering how to collect metrics were: 1) zipkin - https://etherpad.openstack.org/zipkin-tracing 2) python's cprofile 3) newrelic 4) logs have request duration time in them- maybe use splunk somehow? I think we can profile performance during unit tests and tempest tests. Once we have some baseline metrics we can turn on/off features like ldap, pki, etc and eventually do performance testing as a CI gate.
