Hello all,
I wonder why that difference or if I'm doing something wrong.
Regards,
I'm been using cephfs for a while but never really evaluated its performance.
As I put up a new ceph cluster, I though that I should run a benchmark to see if I'm going the right way.
By the results I got, I see that RBD performs a lot better in comparison to cephfs.
The cluster is like this:
- 2 hosts with one SSD OSD each.
this hosts have 2 pools: cephfs_metadata and cephfs_cache (for cache tiering).
- 3 hosts with 5 HDD OSDs each.
this hosts have 1 pool: cephfs_data.
all details, cluster set up and results can be seen here: https://justpaste.it/167fr
I created the RBD pools the same way as the CEPHFS pools except for the number of PGs in the data pool.
I wonder why that difference or if I'm doing something wrong.
