Last year ORMeter site made a lot of noise. Its authors have done what many asked in various forums. They compared the performance of majority popular ORM on .Net platform. As a result developer's opinions were divided. Someone said that tests are out of touch with reality, someone has found another argument for infinite holy wars, someone thought that the site just advertise own product, etc. But there was another result. The developers around the world found out about such ORM as BLToolkit thatin almost all tests proved to be a leader. It is time to get to know it better.
