I'd like to share my research on understanding of this behavior.

Hello Sage,
I recall that lookups-by-inode could historically return -ESTALE if the
inode in question was no-longer in the MDS cache. This presumably
removes that deficiency?

hi noah,
Some results for the read tests:
I set client_readahead_min=4193404 which is the default for hadoop
dfs.datanode.readahead.bytes also. I ran the dfsio test 6 times each for
HDFS, Ceph with default read ahead & ceph with readahead=4193404. Setting
read ahead in ceph did give about a 10%

Ran the DFS IO write tests:
- Increasing the journal log size did not make any difference for me ... i
guess the number i had set was sufficient. For the rest of the tests I kept
it at a generous 10GB.
- Separating out the journal from the data disk did make a difference as
expected. Unfortunately
