I interpret that in linux, 5000000 seems a divide for qsortpdq. Before
that number, it wins, after that, bsd wins more. On SunOS, qsortpdq takes
the lead till the last second -- I suspect this is due to the rand()
function:
Linux - #define RAND_MAX 2147483647SunOS - #define RAND_MAX 32767
So in SunOS, the data actually not that scattered - so more favourate for
sorted() or reversed() check?
