We have revoke_by_id option enabled by default and as we have discussed with Keystone team (Alexander Makarov) it can seriously affect performance and also we can see the following errors in keystone logs during the Tempest tests execution on CI:

To fix the issue we need to set the parameter [token]revoke_by_id=False, it will increase the performance and probably fix the issue with 401 errors on CI (we are going to test it).
