Setup to test the mbps of memmove

I wanted to test how fast memmove can move bytes.

What would be the best way to do this?

I was thinking of using malloc to create 2 arrays (a source and a dest)

#include <time.h>  #define MEM_SIZE_16MB   ( 16 * 1024 * 1024 )        clock_t t;    char *source = malloc(MEM_SIZE_16MB * sizeof(char));  char *dest = malloc(MEM_SIZE_16MB * sizeof(char));    t = clock();  memmove(dest, source, sizeof(source))  t = clock() - t;  double time_taken = ((double)t)/CLOCKS_PER_SEC;    double mbps = 16/time_taken;    free(source);  free(dest);  

Would this be a good setup?
