Yes. CPU Load in Ceph for rand. 4k writes can be dropped by 50% when
disabling all debug setting (see my last post on ceph mailinglist).
I just see it, great,I'll test it on my side :)
(how many ssds - nodes ?) I hope that Intank is working on random io
performance.
I have 5 nodes with 4 SSDs each.
I don't understand why we can't get more iops, if they are no cpu or disks
bottleneck... (or they are locks somewhere ....)
I really would like to known if iops scale with the number of nodes...
To me yes. With 3 Nodes i had a max of 10.000 iops.
