If you are readers of my blog, then you know that I write a lot of ORMs. Naturally, I could not miss a post of Sam Saffron about developing by him own lightweight ORM called Dapper. For those who do not know Sam, I want to point out that he is one of the key developers of Stackoverflow. In addition, before he wrote the post it was known about Stackoverflow's architecture that it was included the Linq-to-Sql. This is the main reason why I, like other developers, began to study the source code for Dapper. As it turned it a little, or rather just one file. Perusing it I thought whether it can be done even faster or not? Boost Sam's code was not simply too high quality it was written. Results are in this post.
