Hi list,
I am trying to understand if, and how, to increase synchronous write
performance to an XFS filesystem.
A common scenario is an NFS-exported directory with sync writes enabled
(default). With EXT4, it is possible to mount it using the
"data=journal" option which, by eliminating small seeks, give a very
nice performance boost (at least with short write spikes).
AFAIK, XFS only journals metadata, never user data alone. There is
nothing I can do to increase its sync write performance in this case?
Short of using a powerloss-protected controller/drives with writeback
caches enabled, of course...
Thanks.
