  1. Answer the following conceptual questions:

    • What is a micro-benchmark?
    • What is working set size, and how might it affect the results of storage benchmarks?
    • What is the reason for studying the price/performance ratio?
  2. Choose a micro-benchmark and perform the following tasks:

    • Scale a dimension (threads, I/O size, ...) and measure performance.
    • Graph the results (scalability).
    • Use the micro-benchmark to drive the target to peak performance, and analyze the limiting factor.
