[Openstack] [SWIFT] Bad replication performance after adding new drives

Hi, I have a swift cluster with 7 storagenodes. The cluster has about 360 million objects with an average size of 170kB. I added 2 new harddrives to my cluster and now it takes weeks for one replication round: Feb 10 09:40:41 storage-node1 object-replicator: 7698658 suffixes checked - 9.03% h

Re: [Openstack] [SWIFT] PUTs and GETs getting slower
