[linux-lvm] Performance impact of LVM

Hmm. Yeah, this setup i'm using was created and thereafter never changed
(yet). So i guess it should all still be contiguous...

Thanks for the info though. I'll see if i can do some tests when i get
my new hardware to play with. But as said before, it's probably not even
measurable. The added latency that is...

Thanks!
Sander.
