Disabling Nagle algorithm in Kestrel Web Server of ASP.Net Core 2.2

Question

KestrelServerOptions.NoDelay is not available in .NET Core 2.2 any more.

Please how can I disable Nagle algorithm in Kestrel Web Server of ASP.Net Core 2.2?

Answer 1

Disabling Nagle's algorithm is now available at ListenOptions.NoDelay

Here is the code snippet for the same

.ConfigureKestrel((context, options) =>
{
    options.Limits.MaxConcurrentConnections = 100;
    options.Listen(IPAddress.Loopback, 5000, (listenOptions =>
    {
        listenOptions.NoDelay = false;
    }));
});

Answer 2

listenOptions.NoDelay = false; Means enable Nagle algorithm. Set to false to enable Nagle's algorithm for all connections. Defaults to true.

Answer 3

I can't post a comment, but wanted to share this as I couldn't find the answer until I went through the commit history for ListenOptions.cs here . For .Net Core 3.0/3.1, "NoDelay" has moved to SocketTransportOptions.

Example:

var builder = new WebHostBuilder().UseKestrel(kestrelServerOptions => {...}).UseSockets(socketTransportOptions => { socketTransportOptions.NoDelay = false; }).Build();
