I've found nothing related in Apache logs,
I believe it's something related to Radosgw,
Anyone else tested the same thing on owned Radosgw?

Hi Hadi,
Can you tell me a bit about the tests you are doing and seeing poor
performance on?

My test is so simple,
On a cluster with 3 MON, 4 OSD, 1 RGW I can't download a big file from two
different clients concurrently,
One of them will wait till the other finish downloading it.

Sounds like an issue with your apache config. How did you install your
apache? What distribution are you running on? Are you using it as
mpm-worker? Do you have non-default radosgw settings?

Strange! I'm not sure I've actually ever seen two concurrent downloads
fail to work properly. Is there anything unusual about the setup?

I'm running Ubuntu 12 on all my nodes and I've just installed every package

I'm not really an apache expert, but you could try looking at the apache
and rgw logs and see if you can trace where the 2nd request is hanging
up. Also, just to be sure, both clients can download data
independently, just not together?

You specify the relative performance, but what the actual numbers that you're
seeing? How many GETs per second, and how many PUTs per second do you see?

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
the single rados bench
output!
Any other suggestion ?
Thanks Regards

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
wip-6286 branch as we have a rather major performance improvement in it
