DESCRIPTION
|
|
|
|
Many years ago, a floating-point benchmark called whetstone was popular
|
|
for benchmarking FORTRAN programs. Nowadays, an integer benchmark called
|
|
dhrystone is widely used for benchmarking UNIX systems. This is it. Be
|
|
warned, however, that dhrystone 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.
