Hello, I have been trying cephfs on the latest 12.x release. Performance under cephfs mounted via kernel seems to be as expected maxing out the underlying storage / resources using kernel version 4.13.4. However when it comes to mounting cephfs via ceph-fuse looking at performance of 5-10% for the same read & write operations as per the kernel mount. 1/ Is there any options or optimizations that anyone has used or can suggest to increase ceph-fuse performance?
2/ The reason for looking at ceph-fuse is the benefit of cephfs quotas (currently not enabled), will it ever be possible for enable quotas on the kernel mount or is this something not possible with the current implementation of quotas? From the few articles ive read online about ceph-fuse some have found the performance to be the other way around. Cheers |
