Domu disk performance ideas

["Sam Fourman Jr." <sfourman%gmail.com@localhost>]

We are considering using NetBSD as a dom0 for 25 some HVM windows XP machines
in a production environment (Municipal workstation images)

I came across the following link, I realize that it is dated, and I
wonder how relevent the stats are now
say NetBSD -CURRENT dom0 vs recent CentOS
http://kuparinen.org/martti/comp/xendom0/xendom0.html#5

on the NetBSD side though, is partition backed Domu's faster than file
image based?
can hardware RAID 0 make file image based domu's faster?

What about NetBSD LVM? I never used it but I noticed it was a topic here
http://www.ukuug.org/events/eurobsdcon2009/talks/#hamsik


I would be interested to hear from anyone running Xen in a Production
environment
Eg, how many domu's and simple server hardware specs. I would like to
present these
findings in a report to make my case for using NetBSD over Linux as a Xen Host.

Thank you for any input
