Hi all,
this is a note which can be useful to someone searching for the same
thing: using "ftype=1" at mkfs time (which is, by the way, the default
for CRC-enabled filesystem) greatly speed-up stat/find operations.
On a test case with 1.000.000 files and 1000 total directories, "find
/mnt/xfs" time has fallen from ~70 to ~20 seconds.
As a side question: there is no method/possibility to enable ftype=1 to
an already existing filesystem, right?
Thanks.

Cheers,

Ok, very clear.
Thank you for taking the time to explain, Dave.
