XPnet created a whitepaper which analyze and describes the performance characteristics of Altiris SVS Pro, Citrix XenApp, Microsoft App-V and VMware ThinApp. Although the tested application set is limited it still gives a nice view of the performance characteristics of different Application Virtualization solutions.
VMWare commission the study, but did not aid or influence the results. VMWare chose Xpnet to study AppVirt performance because they developed Clarity Suite which is a fairly well known Office benchmarking application and because it’s freely available anyone can reproduce their results. This is the first real whitepaper which investigates the performance impact of various Application Virtualization solutions. My personal feeling is that there are more real independent tests to come..

UPDATE; The topic 'Performance analysis' is very interesting. The research organization XPnet isn't that interesting; read it here: http://www.zdnet.com/blog/btl/why-we-dont-trust-devil-mountain-software-and-neither-should-you/31024 and
