creates a memory mapping to the file and then reads the mapping in an unrolled
loop similar to that used in bw_mem_rd(8).
The benchmark is intended to be used on a file
that is in memory, i.e., the benchmark is a reread benchmark. Other
file benchmarking can be done with
specification may end with ``k'' or ``m'' to mean
kilobytes (* 1024) or megabytes (* 1024 * 1024).
Output format is "%0.2f %.2f\n", megabytes, megabytes_per_second, i.e.,
This benchmark should move approximately the reported amount of memory.
