Keep an eye on the new thread OSD (and probably other settings) not
being picked up outside of the [global] section. You may be running
into something similar.

I assume you added more clients and checked that it didn't scale past
that?
Yes, correct.
You might look through the list archives; there are a number of
discussions about how and how far you can scale SSD-backed cluster
performance.
I have look at those discussions before, particular the one
Hi,
With 0.86, the following options and disabling debugging can improve

Decrease the rbd debug level from 5 to 0, and almost all the debugging and
logging are disabled. It doesn't help.
ceph tell osd.* injectargs '--debug_rbd 0\/0'

Thanks for the detailed information. but I am already using fio with rbd

At least historically, high CPU usage and likely context switching and
lock contention have been the limiting factor during high IOPS workloads
on the test hardware at Inktank (and now RH). I ran benchmarks with a
parametric sweep of ceph parameters a while back on SSDs to see if
changing any
Sure Mark, I saw that thread last night. It will be interesting to see the
resolution.
Thanks,
