Random Number Generator

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

The test parameter N is the number of random numbers generated.

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.
