Thanks Jamie,
I have not tried bonnie++. I was trying to keep it to sequential IO for
comparison since that is all Rados bench can do. I did do a full io test
in a windows vm using SQLIO. I have both read/write sequential/random for
4/8/64K blocks from that test. I also have access to a Dell E
The iflag addition should help with at least having more accurate reads via
dd, but in terms of actually testing performance, have you tried sysbench
or bonie++?
I'd be curious how things change with multiple io threads, as dd isn't
necessarily a good performance investigation tool (you're rather
Thanks Jamie,
I tried that too. But similar results. The issue looks to possibly be
with the latency but everything is running on one server so logiclly I
would think there would be no latency but according to this there may be
something that is causing slow results. See Co-Residency

I thought I'd just throw this in there, as I've been following this

I don't have a deep, offhand recollection of the caching mechanisms at play
here, but assuming you want a solid synchronous / non-cached read, you
should probably spe
Hi Mark,
It's a test cluster and I will try with the new release.
As I mentioned in the mail, I think number of rados client instance is the
limitation. Could you please let me know how many rados client instance the
radosgw daemon is instantiating ? Is it configurable somehow ?
Thanks & Regard

Hi,
A couple of things that might be worth trying:
use multiple containers in swift-bench. Newer versions should support
this. Also, if this is a test cluster, you may want to try the ceph

when dealing with small object
Hi,
I am running Ceph on a 3 node cluster and each of my server node is running 10
OSDs, one for each disk. I have one admin node and all the nodes are connected
with 2 X 10G network. One network is for cluster and other one configured as
public network.
All the OSD journals are on SSDs.

Mike,
So I do have to ask, where would the extra latency be coming from if all my

every SSD tweak in the book. The primary concerning issue I see is with

Hi Yehuda / Mark,
Thanks for the information! We will try keystone authentication again when
the next dumpling dot release is out.
As for "ceph cache", are you referring to "rgw_cache_enabled"? If so, we
don't have that set in our ceph.conf so should in theory be using it
already.

The name seems to imply that it should be settable per pool. Is that possible
now?

Hi,
I'm using CephFS 0.67.3 as a backend for Hypertable and ElasticSearch.
Active reading/writing to the cephfs causes uncontrolled OSD memory growth
and at the final stage swapping and server unavailability.
To keep the cluster in working condition I have to restart OSD's with
excessive memory co
