This is the original White Paper that used the phrase "Perceived Performance", written back in 2003.
This White Paper explains a concept we are often describing to customers - "Perceived Performance". In this paper, we describe a different methodology which should be used when performance tuning a Terminal Server, and why. This popular paper seems to have struck a chord with people interested in system performance.
This paper was written on day in a fit of rage one evening over yet another system administrator that had a performance problem but didn't really know what to do. I had no idea how important this paper would become!
