  20. .PP
  21. Many years ago, a floating-point benchmark called fIwhetstonefR was
  22. popular for benchmarking FORTRAN programs.
  23. Nowadays, an integer benchmark called fIdhrystonefR is widely used
  24. for benchmarking UNIX systems.
  25. This is it.
  26. Be warned, however, that fIdhrystonefR is entirely CPU bound, and
  27. goes blindingly fast on machines with high-speed caches.
  28. Although this is a good measure for programs that spend most of their
  29. time in some inner loop, it is a poor benchmark for I/O bound applications.
