Like this:
- ComplexStreamsBenchmark_10000_1000000
- ComplexStreamsBenchmark_1_1000
- SimpleStreamsBenchmark_10000_1000000
- SimpleStreamsBenchmark_1_1000
Thats because different number of items requires different units to measure it. For example measuring perfomance on 1000000 items in ops/us will result on really large values and therefore large error level. So I decided to split benchmarks by number of items on which they run.
If anyone knows better solution -> feel free craete PR and submit it.
