I'd be more concern with your confusing tests instead of your english

So you mean you use the SAME physical server, once as Xen dom0m and
once more as vmware? If yes, what versions/variant are they?. e.g.:
- XCP/xen server
- Centos5
- Opensuse 11.2
- vmware server or esxi, and which version

Do you know what optical disk is? http://en.wikipedia.org/wiki/Optical_disk
I highly doubt that's really what you mean.

Also how are you sharing the NAS? nfs? iscsi? smb?

I have to say, without the answer to the things I asked, your test
results is somewhat useless.
It's not really something new if a HVM domU without PV drivers is
WAAAAAAAAAAAAAAAY much slower compared to native or even vmware VM.
