 For reasons outlined [in this blog post](https://github.com/ServiceStackV3/mythz_blog/blob/master/pages/344.md) I decided to re-use *TypeSerializer's* text processing-core to create ServiceStack.JsonSerializer - the fastest JSON Serializer for .NET.
-Based on the [Northwind Benchmarks](http://mono.servicestack.net/benchmarks/) it's *3.6x* faster than .NET's BCL JsonDataContractSerializer and *3x* faster then the previous fastest JSON serializer benchmarked - [JSON.NET](http://json.codeplex.com/).
