Here are the numbers copied from vincent reply that concinced me that the data
is illogical
2830 is time for one processor(position 1)
1415 is time for 2 processors(position 1)

procs:  1 , 2 , 4 , 8 , 16
pos
1       2830  1415 832 435 311
2       2849 1424 791 438 274
3      3274 1637 884 467 239
4      2308 1154 591 349 208
5      1584 792 440 243 178
6      4294 2147 1160 670 452
7     1888 993 524 273 187
8      7275 3637 1966 1039 680
9     3940 1790 1094 635 398
10   2431 1215 639 333 187
11   3062 1531 827 425 247

You can see that in almost every position the time of 2 processors is exactly
half of the time of 1 processors.

It does not make sense because it is known that the speed improvement from more
than one processor is not constant.
