3 dhrystone \- integer benchmark
18 .EX "dhrystone" "Run the dhrystone benchmark"
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.
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.
