          Benchmarking thread-safe ways to generate a single random normalized gaussian value in Kotlin/JVM.

Comparing:

- `java.util.Random().nextGaussian()`

  - **[A1]** creating new `Random` object instance for each sample

  - **[A2]** reusing `Random` in `synchronous` block

- **[B]** `java.util.concurrent.ThreadLocalRandom.current().nextGaussian()` 

- **[C]** `kotlin.math.Random.nextDouble(...)` with [Box–Muller transform](http://www.java2s.com/example/java-utility-method/gaussian/gaussian-973fd.html) extension 

- `org.apache.commons.rng.simple.ThreadLocalRandomSource.current(...)`

  - **[D1]** with new `ZigguratSampler` instance for each sample

  - **[D2]** with Box–Muller transform extension 

- **[E]** reusing `org.apache.commons.math3.random.SynchronizedRandomGenerator`

See [source](https://github.com/rtmigo/rng_benchmark_kt/blob/dev/src/main/kotlin/Main.kt) for details.

- SINGLE_THREAD: Accessing thread-safe generator from single thread

- LARGE_COROUTINES: Starting six coroutines in parallel and generating many

  samples in each of them

 

- SMALL_COROUTINES: Starting and stopping parallel coroutines multiple times to

  generate single samples in each of them

Percentage is time, lower values are better (faster).
