and they improve performance, let me know.

Well, it's the same for rbd, what's your stripe count set to? For a small
system, it should be at least the # of nodes in your system.As systems
get larger, there's limited returns... I would imagine there would be some
OSD caching advantage

Cern noted that they need to reformat to put the Journal in a partition
rather than on the OSD's filesystem like you did. See

When I saw that ceph disk prepare created a journal partition, I thought it
was stupid to force a

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,
Hi,
I am also searching for tuning the single thread performance.
You can try following parameters:
[osd]
osd mount options xfs =
rw,noatime,inode64,logbsize=256k,delaylog,allocsize=4M
osd_op_threads = 4
osd_disk_threads = 4
