Subject: TOO SLOW data write speed and delete.. NEED HELP
Date: Tue, 13 Mar 2012 10:39:33 +0000 (UTC)	[thread overview]
Message-ID: <loom.20120313T113524-750@post.gmane.org> (raw)

Hi all,
Can someone PLEASE help me to understand why data copying (simple cp
or rsync) is SO slow in CEPH ? And delete command (\rm -rf) for removing
a small (175M) directory is taking so much of time. Because of this,
i am not able to complete evaluation of ceph using my actual workload. 

I am hereby requesting all to help me in finding out the reason for 
slow write/delete in my ceph cluster. I am really trying hard to 
complete the evaluation with actual workload but not able to copy the
data whats required for evaluation to ceph cluster bcz of slow copy.

I really appreciate any help on this.

Thanks in advance
Madhusudhan
