Public bug reported: 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. ** Affects: nova Importance: Medium Assignee: John Garbutt (johngarbutt) Status: In Progress ** Tags: scheduler ** Changed in: nova Status: New => Triaged ** Changed in: nova Importance: Undecided => Medium -- You received this bug notification because you are a member of Yahoo!
