Has anyone looked at a comparison of :

LVM striping   vs   SW RAID0  vs  dm-multipath and PAV

I would suspect that LVM Striping and SW RAID0 will have similar
performance characteristics since they are mostly using device mapper
under the covers nowadays. LVM is more flexible, but is the code path
also longer than SW RAID0 ?

And how does doing I/O to 3 mod-3 volumes striped through LVM compare
with doing multipathed I/O to a single mod-9 with one base and two
aliases?
