Mediatr behaviors order

[Fabman08]

Hi all!
I'm still studing this awesome architecture and I've a question about Mediatr behaviors order.

Looking at DependencyInjection file in Application project the code is the following

services.AddMediatR(cfg => {
    cfg.RegisterServicesFromAssembly(Assembly.GetExecutingAssembly());
    cfg.AddBehavior(typeof(IPipelineBehavior<,>), typeof(UnhandledExceptionBehaviour<,>));
    cfg.AddBehavior(typeof(IPipelineBehavior<,>), typeof(AuthorizationBehaviour<,>));
    cfg.AddBehavior(typeof(IPipelineBehavior<,>), typeof(ValidationBehaviour<,>));
    cfg.AddBehavior(typeof(IPipelineBehavior<,>), typeof(PerformanceBehaviour<,>));
});

Taking a look in PerformanceBehaviour the code is

public async Task<TResponse> Handle(TRequest request, RequestHandlerDelegate<TResponse> next, CancellationToken cancellationToken)
{
    _timer.Start();

    var response = await next();

    _timer.Stop();
.
.
.

Maybe the last position is not the correct one.
I think the right position is the second, after UnhandledExceptionBehaviour, isn't it?

Thank you!
