Thanks,
this gives another burst for iops. I'm now at 23.000 iops ;-) So for
random 4k iops ceph auth and especially the logging is a lot of overhead.
How much difference did disabling auth make vs only disabling logging?
disable debug logging: 3000 iops
disable auth logging: 2000 iops
Is anybody in the ceph team also interested in a call graph of kvm when
VM is doing random 4k write io?
