 # ServiceStack JsonSerializer
 
+Benchmarks for .NET's JSON Serializers are available at: [servicestack.net/benchmarks/](http://www.servicestack.net/benchmarks/)
+
 ServiceStack's JsonSerializer is optimized for serializing C# POCO types in and out of JSON as fast, compact and cleanly as possible. In most cases C# objects serializes as you would expect them to without added json extensions or serializer-specific artefacts.
 
 JsonSerializer provides a simple API that allows you to serialize any .NET generic or runtime type into a string, TextWriter/TextReader or Stream.
