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