Yes, performance optimizations will be fun in the near future. VMs, thin
provisioning, NetApps WAFL, LVM, funny disk layouts, all can do things
completely different than our "old school" thinking. I wonder when
there's gonna be an I/O scheduler that just elevates the I/O from a VM
to the real host, so that the host itself can optimize and align. After
all, a VM has no idea of the storage. That's why already now you can
choose "noop" as the scheduler in a VM. I guess there will be a
"virtualized" scheduler once, but we will see.
