Performance values are given only as a general guidance and actual performance may vary a lot. This depends largely on the burst compiler and how the calling code can be vectorized with the RNG itself.
All values on this page are for generating a single random number value in nanoseconds. The values have been created in tight loops while calculating statistical values on them. The statistical values are kurtosis, skewness and mean. This restricts the compiler in terms of optimization, but its more accurate to real world use. Other RNG tests usually sum up the output of the RNG only, which can be optimized to a single instruction.
Each test was run in 10 rounds, doing 3 warmup rounds (which aren't timed) first. Each round retrieved 10 million random numbers. The tests where run in single thread. The variance for each timing is less than a nanosecond for burst. For IL2CPP and Mono the variance is usually less than 5 nanoseconds.
These numbers are only as a general guidance and numbers within your algorithms may be completely different.
