The great thing about tranparent page sharing is that it has almost no impact on performance. In fact, for many workloads, TPS can INCREASE performance because the hypervisor will have less memory to manage. You can see results from TPS performance testing we published that show just how well it performs in the VMware paper here: http://www.vmware.com/resources/techresources/10062
The combination of TPS and VDI is extremely powerful in letting you run many more client VMs with no performance impact. It’s the closest thing to a “free lunch” in software you’re likely to find. I’m still waiting to hear directly from someone at Citrix on the settings they used in this testing.
