OS: CentOS 6.5
Version: Ceph 0.79
Hi, everybody!
I have installed a ceph cluster with 10 servers.
I test the throughput of ceph cluster in the same datacenter.
Upload files of 1GB from one server or several servers to one server or several
servers, the total is about 30MB/s.
That is to say, there is no difference between one server or one cluster about
throughput when uploading files.
How to optimize the performance of ceph object storage?
Thanks!

Info about ceph cluster:
4 MONs in the first 4 nodes in the cluster.
11 OSDs in each server, 109 OSDs in total (one disk was bad).
4TB each disk, 391TB in total (109*4-391=45TB.Where did 45TB space?)
1 RGW in each server, 10 RGWs in total.That is to say, I can use S3 API in each
Server.
