Need more speed? Let's compile with FastExpressionCompiler.

Installation

Getting the package:

     PM> Install-Package FastExpressionCompiler

Then add following code on start up

TypeAdapterConfig.GlobalSettings.Compiler = exp => exp.CompileFast();

That's it. Now your code will enjoy performance boost. Here is a current benchmark snapshot:
