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
Excellent job! Looks like this could make a big difference for certain workloads. How much data can it store before it switches away from inlining the data?
