.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.
