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
