Huge caveat; it's only faster than Dapper after the 1st query when it's built up the cached metadata, and only if you're not using referenced objects or child collections.
The speed comes from dynamically emiting IL for the object population methods.
Ahhh gotcha. Still though, very cool looking project! Having the option to do LINQ-style queries would be nice. I find that Dapper Rainbow rarely satisfies my needs outside of basic CRUD operations.
