Subject: Performance results on inline data support
Date: Mon, 30 Sep 2013 16:34:04 +0800	[thread overview]
Message-ID: <5249377C.8030003@ubuntukylin.com> (raw)

Hi,
   We did a performance test on inline data support, the Ceph cluster is 
composed of 1 MDS, 1 MON, 6 OSD on a HPC cluster. The program is simple,
there are 1000 - 3000 files with each being 1KB. The program repeated 
the following processes on each file: open(), read(), close(). The total 
time is measured with/without inline data support. The results are as 
follows (seconds),

#files  without    with
1000    17.3674	  8.7186
2000    35.4848	  17.7646
3000    53.2164	  26.4374

Cheers,
Li Wang
