Does (Cache) Size Matter, Continued...

Now for this file, I get results that make sense:

bash-3.2$ ./tst_ar4 -h pr_A1_50_16_64.nc 
cs[0] cs[1]  cs[2] cache(MB)  deflate  shuffle  read_hor(us)  read_time_ser(us)
50    16    64    4        1    0        157932        155803
50    16     64    16         1    0        3473         155237
50    16    64    32         1    0        3479        146510
50    16    64    64        1    0        3487        120306
50    16     64    128        1    0        3499         64149

Now the best performance comes from the largest cache.
