# Random Interleaving
|
|
|
|
[Random Interleaving](https://github.com/google/benchmark/issues/1051) is a
|
|
technique to lower run-to-run variance. It randomly interleaves repetitions of a
|
|
microbenchmark with repetitions from other microbenchmarks in the same benchmark
|
|
test. Data shows it is able to lower run-to-run variance by
|
|
[40%](https://github.com/google/benchmark/issues/1051) on average.
|
|
|
|
To use, you mainly need to set `--benchmark_enable_random_interleaving=true`,
|
|
and optionally specify non-zero repetition count `--benchmark_repetitions=9`
|
|
and optionally decrease the per-repetition time `--benchmark_min_time=0.1`.
