ioxide.Kestrel

An ASP.NET Core Kestrel transport backed by the ioxide io_uring runtime. One reactor (io_uring ring) per core, SO_REUSEPORT load-balanced, with Kestrel's entire request loop pinned to the reactor thread — no ThreadPool hop on the hot path.

Usage

var builder = WebApplication.CreateBuilder(args);

builder.WebHost.UseIoxide();   // replaces Kestrel's default sockets transport

var app = builder.Build();
app.MapGet("/", () => "Hello, World!");
app.Run();

Options:

builder.WebHost.UseIoxide(o =>
{
    o.ReactorCount = Environment.ProcessorCount;          // rings/threads (default: ProcessorCount)
    o.ConfigureServer = cfg => cfg with { RingEntries = 8192 };   // tune the underlying ioxide ServerConfig
});

How it works

Each accepted connection is bridged to Kestrel through a System.IO.Pipelines duplex whose reader schedulers route continuations onto the owning reactor thread. A recv pump copies received bytes into the inbound pipe and a send pump drains Kestrel's response into the connection's send slab, so recv → HTTP parse → handler → send all run on a single ring thread.

Requirements

  • Linux with io_uring (kernel 6.x recommended).
  • .NET 11.

Inline execution note: like any thread-per-core transport, application middleware runs on the reactor thread. Blocking work in a handler stalls every connection on that reactor — keep handlers async.
