[ceph-users] 回复: half performace with keyvalue backend in 0.87

Looks like the writte performance of keyvalue backend is bad than file store backend with version 0.87 for my curent cluster, the writteing speed only have 1.5MB/s - 4.5MB/s 发件人： ceph-users 发送时间： 2014-10-31 08:23 收件人： ceph-users

Also found the other problem is: the ceph osd directory has millions small files which will cause performance issue 1008 => # pwd /var/lib/ceph/osd/ceph-8/current 1007 => # ls |wc -l 21451 发件人： ceph-users 发送时间： 2014-10-31 08:23 收件人： ceph-users
