PERFOMANCE BENCHMARKS

1. Standard set of tests, serialization to class instances and tuples with various fields types

Test Query and Test Class

10 fields wide query on PostgreSQL 13 with parametrized number of records.

• Query:

    select 
        i as id1, 
        'foo' || i::text as foo1, 
        'bar' || i::text as bar1, 
        ('2000-01-01'::date) + (i::text || ' days')::interval as datetime1, 
        i+1 as id2, 
        'foo' || (i+1)::text as foo2, 
        'bar' || (i+1)::text as bar2, 
        ('2000-01-01'::date) + ((i+1)::text || ' days')::interval as datetime2,
        'long_foo_bar_' || (i+2)::text as longfoobar, 
        (i % 2)::boolean as isfoobar
    from 
        generate_series(1, {records}) as i

• Test Class

    public class PocoClass
    {
        public int Id1 { get; set; }
        public string? Foo1 { get; set; }
        public string? Bar1 { get; set; }
        public DateTime DateTime1 { get; set; }
        public int Id2 { get; set; }
        public string? Foo2 { get; set; }
        public string? Bar2 { get; set; }
        public DateTime DateTime2 { get; set; }
        public string? LongFooBar { get; set; }
        public bool IsFooBar { get; set; }
    }

Test Methods

Dapper

Normal Dapper serialization, used as baseline for ratio.

foreach (var i in connection.Query<PocoClass>(query))
{
}

Dapper_Buffered_False

Unbuffered Dapper serialization.

foreach (var i in connection.Query<PocoClass>(query, buffered: false))
{
}

Norm_NameValue_Array

Non-generic Read method that yields name and value tuple array.

foreach (var i in connection.Read(query))
{
}

Norm_PocoClass_Instances

Standard Norm serialization to class instances. Equivalent to unbuffered dapper query.

foreach (var i in connection.Read<PocoClass>(query))
{
}

Norm_Tuples

Norm serialization to unnamed tuples.

foreach (var i in connection.Read<int, string, string, DateTime, int, string, string, DateTime, string, bool>(query))
{
}

Norm_Anonymous_Types

Norm serialization to anonymous type instances.

foreach (var i in connection.Read(new
{
    id1 = default(int),
    foo1 = default(string),
    bar1 = default(string),
    datetime1 = default(DateTime),
    id2 = default(int),
    foo2 = default(string),
    bar2 = default(string),
    datetime2 = default(DateTime),
    longFooBar = default(string),
    isFooBar = default(bool),
}, 
query))
{
}

Norm_Named_Tuples

Norm serialization to named tuples.

foreach (var i in connection.Read<(int id1, string foo1, string bar1, DateTime datetime1, int id2, string foo2, string bar2, DateTime datetime2, string longFooBar, bool isFooBar)>(query))
{
}

Norm_PocoClass_Instances_ReaderCallback

Standard Norm serialization to class instances (equivalent to unbuffered dapper query), but, containing a reader callback lambda function which only uses a reader to read the first field.

foreach (var i in connection.Read<PocoClass>(query, o => o.Ordinal switch
{
    0 => o.Reader.GetInt32(o.Ordinal),
    _ => null
}))
{
}

Norm_Tuples_ReaderCallback

Standard norm serialization to unnamed tuples, but, containing a reader callback lambda function which only uses a reader to read the first field.

foreach (var i in connection.Read<int, string, string, DateTime, int, string, string, DateTime, string, bool>(query, o => o.Ordinal switch
{
    0 => o.Reader.GetInt32(o.Ordinal),
    _ => null
}))
{
}

Norm_Named_Tuples_ReaderCallback

Stanard norm serialization to named tuples, but, containing a reader callback lambda function which only uses a reader to read the first field.

foreach (var i in connection.Read<(int id1, string foo1, string bar1, DateTime datetime1, int id2, string foo2, string bar2, DateTime datetime2, string longFooBar, bool isFooBar)>(query, o => o.Ordinal switch
{
    0 => o.Reader.GetInt32(o.Ordinal),
    _ => null
}))
{
}

Command_Reader

Raw data reader approach.

using var command = new NpgsqlCommand(query, connection);
using var reader = command.ExecuteReader();
while (reader.Read())
{
    var instance = new PocoClass
    {
        Id1 = reader.GetInt32(0),
        Foo1 = reader.GetString(1),
        Bar1 = reader.GetString(2),
        DateTime1 = reader.GetDateTime(3),
        Id2 = reader.GetInt32(4),
        Foo2 = reader.GetString(5),
        Bar2 = reader.GetString(6),
        DateTime2 = reader.GetDateTime(7),
        LongFooBar = reader.GetString(8),
        IsFooBar = reader.GetBoolean(9),
    };
}
