They did not run their certain web app with more than 2gb of memory in
any system. They did a test on their machines showing a marked
difference in throughput when moving from 1gb to 2gb, so how about the
64bit advantage of having, say, 16gb of ram?

That and how do we know that their cgi script is well designed without
seeing it?

It's great for them to have that paper though, as they can refer
McDonalds and FedEx to it when those companies wonder about upgrading to
64bit. Instead, NN&A can get some great contracts selling upgrades to
32bit systems.
