20 | .PP
|
---|
21 | Many years ago, a floating-point benchmark called \fIwhetstone\fR was
|
---|
22 | popular for benchmarking FORTRAN programs.
|
---|
23 | Nowadays, an integer benchmark called \fIdhrystone\fR is widely used
|
---|
24 | for benchmarking UNIX systems.
|
---|
25 | This is it.
|
---|
26 | Be warned, however, that \fIdhrystone\fR 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.
