I think Frank is telling a cautionary tale, but from an applications
perspective, so he
may (or may not) be privy to all of the details in his shop. Mark's comments
are (as
usual) spot on. It's a matter of configuring the virtual machines and
applications to
suit your environment. It is also a matter of tuning the environment somewhat
more than
is necessary on other platforms, because usually we're trying to stuff 10
pounds of
stuff into a 5 pound bag.
All of those applications can run exceeding well on Linux for System z.

I, for one, would be **EXTREMELY** interested in seeing some "hard
numbers" to support those assertions. Literally everything I've read
and heard about Linux on z utterly contradicts them. We are considering
a Proof of Concept project to evaluate running Oracle (and possibly
Websphere Application Server) on an IFL (one, initially) with z/VM. If
your shop's assertions above are even remotely close to reality, I am
duty-bound to inform my management that doing so may not be "all peaches
and cream".
