Back to the Win32 Shootout Back to dada's perl lab

N is the number of iterations of the main object instantiation loop.

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.
