Thanks for your efforts. To improve asp.net core results, you can do followings:

1- Change Platform from its default value (AnyCPU) to (X64)

2- Use following code for Program.cs

using Microsoft.AspNetCore.Hosting;
using System.IO;
namespace AspNetCorePerformanceTests
{
    public class Program
    {
        public static void Main(string[] args)
        {
            IWebHost host = new WebHostBuilder()
                .UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseStartup<Startup>()
                .Build();
host.Run();
        }
    }
}

3- In launchSettings.json change environments from Development to Production

Performance gets better, due removing loggers, improving CPU processing, switching from dev to production.
