What is your basis for saying that? At our shop on the M$ servers, no
more than one strategic service is run per server because things lock up
and interact, and no one wants to bounce a box with one zombie and other
important services running. So we're not getting any mileage out of the
boxes at all ... and it's been that way in most of the shops I've
worked in. Everybody expects VMWare to change all that, but I have as
yet to see it.
On POSIX boxes, the first perl program, to pick one, loads the perl
interpreter and all the other perl apps and services use the same block
of code. Not that much different from shared C libraries. The scripts
themselves don't consume that much memory, and most scripting languages
are capable of compiling to byte code.
I don't have any numbers, but I wonder if you do. When I think about
it I can't see much reason to expect that the footprint of several
concurrent scripted apps in the same language would have a much larger
footprint than several C++ programs. I do know that I frequently will
have five or six Tcl/Tk apps running simultaneously without any apparent
dump to VM. Open Office, OTOH (a C++ program IIRC) dims the lights in
the house and emits ozone when it loads.
Does anyone have any real data on this?

I talk about Java and .NET as little as possible, too.
