Definitely Fastest and Zero Allocation JSON Serializer for C#(.NET, .NET Core, Unity and Xamarin), this serializer write/read directly to UTF8 binary so boostup performance. And I adopt the same architecture as the fastest binary serializer, MessagePack for C# that I've developed.This benchmark is convert object to UTF8 and UTF8 to object benchmark. It is not to string(.NET UTF16), so Jil, NetJSON and Json.NET contains additional UTF8.GetBytes/UTF8.GetString call. Definitely means does not exists encoding/decoding cost. Benchmark code is in sandbox/PerfBenchmark by BenchmarkDotNet.
