Title:
  reduce logging in the scheduler to improve performance

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  The current debug logs in the scheduler are at critical points in the
  code, and are causing performance issues.

  After the DB, the scheduler is spending more time doing logging, than
  anything else.

  This was discovered using the
  test_performance_check_select_destination unit test, and modifying it
  to look at when there are around 200 hosts, which is still quite a
  modest size.
