True. But my previous experience in university environments is that SunOS
usually refers to SunOS 2.6 -- and the performance indicates old hardware.

The thing is, compilser optimised versions of the test reveal very little
difference in performance. This may be because the compiler is very good
at optimising sequential annd predictable access to the array. Instead, we
should mimic what we see in the real world: random access.
