When swift has almost zero data and zero real user, but consumes significant amount of the I/O and CPU capacity.

Please tune the defaults to use less than 200 IOPS  and less than 1 cpu core per node in avg, when it is idle (no real user).

Comment 1 Christian Schwede (cschwede) 2016-11-02 13:37:46 UTC

This is basically the same as described in https://bugzilla.redhat.com/show_bug.cgi?id=1381721.

As a fix for that, we did the following changes that are included in latest builds:

Set concurrency to 1 for auditor/replicator/updater
- https://review.openstack.org/#/c/383724/

Throttle update_auditor_status calls
- https://review.openstack.org/#/c/383707/

Closing this bug as duplicate therefore.
