I'm looking into the Citrix environment and have been unable to locate any white papers/guides that are current regarding server sizing. I'm aware that every environment is unique and as Citrix always says you must test in your own environment. I'm just looking for a basic stating point that deals with newer hardware. Everything I've been able to find deals with at most 500mhz machines. I don't know if it is a straight line extrapolation when you get into GHZ plus machines. Any assistance will be appreciated.
