The execution time of the EnableClassInterceptors method is gradually increasing.

The steps to reproduce the problem are:

The source code of the project that can reproduce the problem: https://github.com/maliming/ClassInterceptorTest

Create a simple mvc project and add a lot of controllers.

Controller.cs

public abstract class MyControllerBase : Controller
{
}

[Route("api/testapi/test0api")]
public class Test0ControllerBase : MyControllerBase
{
    [HttpGet]
    [Route("Get")]
    public string TestMethod()
    {
        return "test";
    }
}

[Route("api/testapi/test1api")]
public class Test1ControllerBase : MyControllerBase
{
    [HttpGet]
    [Route("Get")]
    public string TestMethod()
    {
        return "test";
    }
}

//Test100ControllerBase 

Program.cs

public class Program
{
    public static void Main(string[] args)
    {
        var host = Host.CreateDefaultBuilder(args)
            .UseServiceProviderFactory(new AutofacServiceProviderFactory())
            .ConfigureWebHostDefaults(webHostBuilder =>
            {
                webHostBuilder.UseStartup<Startup>();
            })
            .Build();

        host.Run();
    }
}

Startup.cs

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers();
    }

    public void ConfigureContainer(ContainerBuilder builder)
    {
        foreach (var type in Assembly.GetExecutingAssembly().GetTypes()
        .Where(x => typeof(MyControllerBase).IsAssignableFrom(x)))
        {
            var stopwatch = Stopwatch.StartNew();

            builder.RegisterType(type)
                .As(type)
                .EnableClassInterceptors();

            stopwatch.Stop();
            Console.WriteLine(type.Name + " => ElapsedMilliseconds:" + stopwatch.ElapsedMilliseconds);
        }
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseHttpsRedirection();

        app.UseRouting();

        app.UseAuthorization();

        app.UseEndpoints(endpoints => { endpoints.MapControllers(); });
    }
}

My code enables class interception for each controller.

builder.RegisterType(type)
        .As(type)
        .EnableClassInterceptors();

Ideally, the execution time of the EnableClassInterceptorsmethod should be about the same.

But the result is that time is gradually increasing.

This seems to be a problem with castle https://github.com/castleproject/Core/issues/486
