Baseline

In order to scale your results, you need to mark one of your benchmark methods as a baseline. Only one method in class can have Baseline = true applied.

Example

public class Sleeps
{
    [Benchmark]
    public void Time50()
    {
        Thread.Sleep(50);
    }

    [Benchmark(Baseline = true)]
    public void Time100()
    {
        Thread.Sleep(100);
    }

    [Benchmark]
    public void Time150()
    {
        Thread.Sleep(150);
    }
}

As a result, you will have additional column in the summary table:

BenchmarkDotNet=v0.9.0.0
