Hi Christoph,

You're defintively missing the "inode64" mount option, which we've
always recommended, and which finally made it to be the default in
Linux 3.7.
Some other things worth playing with, but which aren't guaranteed to
be a win are:
- use a larger than default log size (e.g. mkfs.xfs -l size=2g)
- use large directory blocks, similar to what you already do for btrfs
(mkfs.xfs -n size=16k or 64k)
Thanks for recommendations.
Right now i'm using this in my ceph setup with 240GB SSDs for each OSD.
May i ask you to comment them? Do they make sense in your eyes?
# i have 12 cores per machine
mkfs.xfs -f -d agcount=12 /dev/sdX2
Mount options: noatime,nodiratime,nobarrier,logbsize=256k,logbufs=8,inode64
Greets,
Stefan
