Having trouble getting a reply from c...@cbt.com so trying ceph-devel list...
To get familiar with CBT, I first wanted to use it on an existing cluster.
(i.e., not have CBT do any cluster setup).
Is there a .yaml example that illustrates how to use cbt to run for example,

Hi all --
Looking for guidance with perf counters...
I am trying to see whether the perf counters can tell me anything about the
following discrepancy
I populate a number of 40k size objects in each of two pools, poolA and poolB.
Both pools cover osds on a single node, 5 osds total.

I will be out of office for a week but will put this on the list of things to
try when I get back.

I've noticed that
* with a single node cluster with 4 osds
* and running rados bench rand on that same node so no network traffic
* with a number of objects small enough so that everything is in the cache
so no disk traffic
we still peak out at about 1600 MB/sec.
