Note
(*) OSprofiler uses specific SQLalchemy cursor events to track what’s going on with the DB layer. This number includes non-real DB requests “SELECT 1”, processed by SQLalchemy itself to make sure that connection to the database is still in place.
Note
Number of DB queries is much bigger for this request comparing with similar Liberty environment. The difference is in keystone_authtoken middleware (and, more specifically, its cache) usage. Although all environments that took part in the research had exactly the same keystone_authtoken middleware configuration, described in the test plan and containing memcache_servers parameter set up, Mitaka environments profiling shows that all OpenStack services that used keystone_authtoken middleware did not use the external Memcached cached token copy. All of them used Keystone API every time REST API request was coming to the OpenStack services. This behaviour needs to be investigated separately.

(*) OSprofiler uses specific SQLalchemy cursor events to track what’s going on with the DB layer. This number includes non-real DB requests “SELECT 1”, processed by SQLalchemy itself to make sure that connection to the database is still in place.
Note
Number of DB queries is much bigger for this request comparing with similar Liberty environment. The difference is in keystone_authtoken middleware (and, more specifically, its cache) usage. Although all environments that took part in the research had exactly the same keystone_authtoken middleware configuration, described in the test plan and containing memcache_servers parameter set up, Mitaka environments profiling shows that all OpenStack services that used keystone_authtoken middleware did not use the external Memcached cached token copy. All of them used Keystone API every time REST API request was coming to the OpenStack services. This behaviour needs to be investigated separately.
