One last note, the reference

leads me to believe that the method used by the octave-forge rand.cc is
reliable. Thanks to everyone for the information, Michael
Thanks for the link.
They report a 4s startup time for MT on a 2.4 GHz machine. I can
assure you this is not the case for randn on octave-forge. We
are definitely not doing what the code in Dynamic Creation
Mersenne Twister (DC) is doing.
Given the long startup time for DC, you need 70 M random numbers
just to break even with the next fastest. Depending on what you
are doing, you may be better off using SPRNG's multiplicative
lagged fibonacci generator (MLFG).
