| For some people, performance of random number generation is an important |
| consideration when choosing a random number generator or a particular |
| distribution function. This page provides numerous performance tests with |
| the wide variety of generators and distributions available in the boost |
| library. |
| |
| The performance has been evaluated on an Intel(R) Xeon(TM) MP |
| CPU 3.66GHz, Gentoo Base System release 1.12.11.1, GCC 4.3.2, |
| glibc 2.9 and on an Intel(R) Core(TM)2 CPU T7600 |
| @2.33 Ghz with Microsoft Windows XP Professional, Service Pack 2 Build |
| 2600, Microsoft Visual C++ 2008 9.0.21022. |
| The speed is reported in million random numbers |
| per second (M rn/sec), generated in a tight loop. |

| Note that the lagged Fibonacci and ranlux_01 generators produce |
| floating-point numbers, whereas all others produce integers. |
