| 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) Core(TM) i7 |
| CPU Q 840 @ 1.87GHz, 1867 Mhz with Visual C++ 2010, Microsoft |
| Windows 7 Professional and with gcc 4.4.5, Ubuntu Linux 2.6.35-25-generic. |
| The speed is reported in million random numbers |
| per second (M rn/sec), generated in a tight loop. |

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