I'm not sure, I known that it can impact performance on osd, but not sure about the client.

I'll tell te question on the mailing list.

Objet: [pve-devel] ceph performance 



I guess we do not have syncfs support in our libc: 

http://ceph.com/docs/master/install/os-recommendations/ 

But the RHEL6.3 kernel includes that syscall. Can we compile ceph using the syscall directly? 

Maybe that is the reason for the bad performance?
