SimdJsonSharp: Parsing gigabytes of JSON per second
Signed assembly package for C# version EgorBo/SimdJsonSharp of lemire/simdjson (by Daniel Lemire and Geoff Langdale - https://arxiv.org/abs/1902.08318) fully ported from C to C#,
Version - 1.7.0
Benchmarks
The following benchmark compares SimdJsonSharp with .NET Core 3.0 Utf8JsonReader, Json.NET and SpanJson libraries.
Test json files can be found here.
1. Parse doubles
Open canada.json and parse all coordinates as System.Double:

Usage
The C# API is not stable yet and currently fully copies the original C-style API
thus it involves some Unsafe magic including pointers.
Add nuget package SimdJsonSharp.Managed (for .NET Core 3.0) or SimdJsonSharp.Bindings for a .NETStandard 2.0 package (.NET 4.x, .NET Core 2.x, etc).
dotnet add package SimdJsonSharp.Bindings
or
dotnet add package SimdJsonSharp.Managed
The following sample parses a file and iterate numeric tokens
byte[] bytes = File.ReadAllBytes(somefile);
fixed (byte* ptr = bytes) // pin bytes while we are working on them
using (ParsedJson doc = SimdJson.ParseJson(ptr, bytes.Length))
using (var iterator = doc.CreateIterator())
{
while (iterator.MoveForward())
{
if (iterator.GetTokenType() == JsonTokenType.Number)
Console.WriteLine("integer: " + iterator.GetInteger());
}
}
UPD: for SimdJsonSharp.Bindings types are postfixed with 'N', e.g. ParsedJsonN
As you can see the API looks similiar to Utf8JsonReader that was introduced recently in .NET Core 3.0
Also it's possible to just validate JSON or minify it (remove whitespaces, etc):
string someJson = ...;
string minifiedJson = SimdJson.MinifyJson(someJson);
