2. www.OASUS.ca What are benchmarks Historical: “...originates from the chiseled horizontal marks that surveyors made in stone structures, into which an angle-iron could be placed to form a "bench" for a leveling rod, thus ensuring that a leveling rod could be accurately repositioned in the same place in the future.” Thursday, November 26, 20152

3. www.OASUS.ca What are benchmarks IT: The act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. Thursday, November 26, 20153

Thursday, November 26, 201512 For this presentation, a USB disk was used to simulate a faulty disk subsystem Results from a regularly run benchmark Suddenly the execution time jumps Running the CPU portion is fine But the disk result is terrible
