Hard to know without more config details such as no of servers, network – GigE or !0 GigE, also not sure how you are measuring, (reads or writes) you could
try RADOS bench as a baseline, I would expect more performance with 7 X 10K spinners journaled to SSDs. The fact that SSDs did not perform much better may mean to a bottleneck elsewhere – network perhaps? From: Marek Dohojda [mailto:mdohojda@xxxxxxxxxxxxxxxxxxx]
Yeah they are, that is one thing I was planning on changing, What I am really interested at the moment, is vague expected performance. I mean is 100MB around normal, very low, or "could be better"?

On Behalf Of Marek Dohojda Sorry I should have specified SAS is the 100 MB :) , but to be honest SSD isn't much faster. On Mon, Nov 23, 2015 at 7:38 PM, Haomai Wang <haomaiwang@xxxxxxxxx> wrote: On Tue, Nov 24, 2015 at 10:35 AM, Marek Dohojda
