Mappers performace testing

Project is used for testing the performance of selected mapper. The aim is to map the data to the data layer (database) on POCO / DTO objects.

Various methods are used to test the most frequent scenarios in simpler information system.

This project uses the library Simple Injector as simple IoC container for autodiscover.

Used mappers:

1. Vanila SqlDataReader
2. Dapper
3. Entity Framework (v. 6.1.3)
4. Entity Framework, used as Unit of Work
5. Entity Framework with Automapper
6. Tiny Mapper
7. Value Injector

Testing datbase

1. MS SQL Server 2014 Express
2. AdventureWorks Sample Database 2014

Results

/	Load large table	Pagged result	Load one row	Load row with joined collection	Combined
Dapper	174 ms	54 ms	3 ms	12 ms	30803 ms
Date Reader	161 ms	40 ms	1 ms	1 ms	30054 ms
Date Reader - closing	154 ms	48 ms	2 ms	1 ms	30672 ms
Entity Framework	648 ms	88 ms	24 ms	57 ms	39498 ms
Entity Framework - AutoMapper	166 ms	45 ms	16 ms	31 ms	35705 ms
Entity Framework - UoF	126 ms	44 ms	6 ms	3 ms	34842 ms
Tiny Mapper	2011 ms	83 ms	5 ms	18 ms	674694 ms
Value Injector	1995 ms	80 ms	6 ms	4 ms	636656 ms

For Tiny Mapper and Value Injector results are not relevant, since in these cases need not take the valid mapping.

Feature work

Added perfmace tests for .Net Core:

1. Vanila SqlDataReader
2. Dapper (.Net Core version)
3. Entity Framework Core
4. Entity Framework Core, used as Unit of Work
5. Entity Framework Core with Automapper
