Playing around a bit with w2k8 tse on running as a VM (single Xeon cpu, 8GB ram) on ESX4 and while it does seem better than my last experience doing this (W2K3 in a VM on ESX 3.0), it is still noticeably slower than the last farm I built on physical servers (W2K3 on HP Proliant 385G4 - dual-opteron, 4GB ram). Mainly just noticing that office 2007 apps take several seconds to load (like on a PC) while on my last farm the app was loaded and ready in under a second - things like that. Has anyone else noticed this, or care? Is it the reality of the overhead of running as a VM, or has W2K8 found to be more sluggish than W2K3? I'm trying to build a case for thin clients and being able to demonstrate noticeably better performance on a TC is a good selling point that I hate to not have. Nope, haven't had a chance to load up with multiple users and see how it scales.
