Centos 7.0 and mismatched swap file
...created at mkfs time. When the workload IO
involves a lot of concurrency, XFS over linear will beat XFS or ext4
over raid0. Whereas for streaming performance workloads, striped raid
will work better. If redundancy is needed, mdadm permits creation of
1+linear, as compared to 10.

You can think of XFS on linear as being something like raid0 at a file
level, rather than at a block level. On a completely empty file system
if you start copying a pile of dozens or more (typically hundreds or
thousands) of f...
