TPC-D Metrics (cont.)

• Composite Query-Per-Hour Rating (QphD)

  • The Power and Throughput metrics are combined to get the composite queries per hour.

• Reported metrics are:

  • Power: QppD@Size
  • Throughput: QthD@Size
  • Price/Performance: $/QphD@Size

• Comparability:

  • Results within a size category (SF) are comparable.
  • Comparisons among different size databases are strongly discouraged.
