| .SH DESCRIPTION
 | |
| .PP
 | |
| Many years ago, a floating-point benchmark called \fIwhetstone\fR was
 | |
| popular for benchmarking FORTRAN programs.
 | |
| Nowadays, an integer benchmark called \fIdhrystone\fR is widely used
 | |
| for benchmarking UNIX systems.
 | |
| This is it.
 | |
| Be warned, however, that \fIdhrystone\fR is entirely CPU bound, and
 | |
| goes blindingly fast on machines with high-speed caches.
 | |
| Although this is a good measure for programs that spend most of their
 | |
| time in some inner loop, it is a poor benchmark for I/O bound applications.
