I have a NFS server with a hardware RAID5 on 3 HDD of 6 TB. I have a system partition with ext4 and a data partition with XFS.

I get only 10 MB/s in write speed on the XFS data partition and 80 MB/s on the system partition.

how are you testing this?

Is there a way to have better performance? Is XFS a good choice in this situation?

it's unlikely that the filesystem is the issue, both xfs and ext4 are more than capable of saturating a 3 disk raid5.
