- Operators may want to tune the ``max_overflow`` and
``wsgi_default_pool_size`` configuration options according
to the investigations outlined in this `mailing list post
<http://lists.openstack.org/pipermail/openstack-dev/2015-December/082717.html>`_.
The default value of ``wsgi_default_pool_size`` inherits from
that of oslo.config, which is currently 100. This is
a change in default from the previous Neutron-specific
value of 1000.
