Hi Abhishek,
Bitrot requires versioning of files to be down on writes.
This was being done irrespective of whether bitrot is
enabled or not. This takes considerable CPU. With the
fix https://review.gluster.org/#/c/14442/, it is made
optional and is enabled only with bitrot. If bitrot
is not enabled, then you won't see any setxattr/getxattrs
related to bitrot.
The fix would be available in 3.11.
Thanks and Regards,
Kotresh H R
