Title:
nova.scheduler.host_manager should cache CONF values
Status in OpenStack Compute (Nova):
Opinion
Bug description:
Performance improvement is possible by caching the values from the
global CONF object that are repeatedly access, including
CONF.scheduler_default_filters and CONF.scheduler_default_filters (see
patch here:
https://review.openstack.org/#/c/85594/3/nova/scheduler/host_manager.py)
and CONF.scheduler_weight_classes.
Avoiding CONF lookups where possible is just good practice.
