Hi Vladimir,
no it is the same on all monitors. Actually I got triggered because I got slow responses on my rados gateway with the radosgw-admin command and narrowed it down to slow respons for rados commands anywhere in the cluster.
Do you have a very large amount of objects. And / or a lot of OMAP data and thus large rocksdb databases? We have seen slowness (and slow ops) from having very large rocksdb databases due to a lot of OMAP data concentrated on only a few nodes (cephfs metadata only). You might suffer from the same thing. Manual rocksdb compaction on the OSDs might help. Gr. Stefan
