Fallacies and Pitfalls
  • Pitfall: Using the peak transfer rate of a portion of the I/O system to make performance projections or performance comparisons.
  • Fallacy: Magnetic storage is on its last legs and will be replaced shortly.
  • Pitfall: Moving functions from the CPU to the I/O processor expecting to improve performance without a careful analysis.
