Columns

A column is a column in the summary table.

Predefined columns

class StatisticColumn
{
    IColumn Mean;
    IColumn StdError;
    IColumn StdDev;
    IColumn OperationPerSecond;
    IColumn Min;
    IColumn Q1;
    IColumn Median;
    IColumn Q3;
    IColumn Max;
    
    IColumn P0;
    IColumn P25;
    IColumn P50;
    IColumn P80;
    IColumn P85;
    IColumn P90;
    IColumn P95;
    IColumn P100;

    IColumn[] AllStatistics = 
                { 
                    Mean, StdError, StdDev, 
                    OperationsPerSecond, Min, Q1, Median, Q3, Max 
                };
}

// Specify a "place" of each benchmark. Place 1 means a group of the fastest benchmarks, 
// place 2 means the second group, and so on. There are several styles:
class Place
{
    IColumn ArabicNumber; // `1`, `2`, `3`, ...
    IColumn Stars; // `*`, `**`, `***`, ...
}

class PropertyColumn
{
    IColumn Type;
    IColumn Method;
    IColumn Mode;
    IColumn Platform;
    IColumn Jit;
    IColumn Framework;
    IColumn Toolchain;
    IColumn Runtime;
    IColumn LaunchCount;
    IColumn WarmupCount;
    IColumn TargetCount;
    IColumn Affinity;
}

Default columns

• PropertyColumn.Type
• PropertyColumn.Method
• PropertyColumn.Mode
• PropertyColumn.Platform
• PropertyColumn.Jit
• PropertyColumn.Framework
• PropertyColumn.Toolchain
• PropertyColumn.Runtime
• PropertyColumn.ProcessCount

Examples

// *** Command style ***
[Config("columns=Min,Max")]
[Config("columns=AllStatistics")]

// *** Object style ***
[Config(typeof(Config))]
public class IntroTags
{
    private class Config : ManualConfig
    {
        public Config()
        {
            Add(Job.Dry);
            // You can add custom tags per each method using Columns
            Add(new TagColumn("Foo or Bar", name => name.Substring(0, 3)));
            Add(new TagColumn("Number", name => name.Substring(3)));
        }
    }

    [Benchmark] public void Foo1() { /* ... */ }
    [Benchmark] public void Foo12() { /* ... */ }
    [Benchmark] public void Bar3() { /* ... */ }
    [Benchmark] public void Bar34() { /* ... */ }
}
