Dhrystone benchmarks for Minix

modified: 21 May 2006


Minix speed tests

Whenever I can get access to a new set of hardware I like to install Minix
and run the dhrystone(1) benchmark. Here are some results. In many cases
Minix is run from a RAM disk to do these tests, I don't actually install 
Minix on the hard disk of every computer I touch!

From the dhrystone(1) man page: 

The integer benchmark called dhrystone is widely used for benchmarking
UNIX systems.  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.
