This is a presentation I gave at the 2008 Annual Hotsos Symposium. Its punny title speaks to the obsession many performance analysts have with the analysis of utilization (U) decoupled from any observations about how a system is actually performing. The preso is a bit of a tirade, but a good rant all-in-all for recalling some of the practices that lead to the common practices of massive over-provisioning and tragically under-managing systems performance.
