The test parameter N is used as a multiple of the input data size. So if N is 2, the test is fed 2 copies of the input data on standard input.

The following graph is similar to the graph on the index page, but here, N is much smaller, and startup costs may be more prominent.

[Note: Values have been normalized to fall in the range of 0-10 for aesthetic reasons. Original value ranges are included on the X-axis.
