I write a Programm in C#. There is a Button on the interface, when I press this Button a Motor starts.  A switch which is connected on I/O Pin 1 works as a counter.

The start and stop from the motor over the C# Interface works great and very fast. But the count from the switch which is connected to the borad has a time delay of 0,5 - 1 second.

Is this normal? Can I make this faster? is there the possibility the press of the switch to write in a register, so that I see the counter works when i press the switch faster?

I have tried some different "Timer" periods from 25 - 200 msec. But the counter is always to slow.

Also, you can register for a GPIO Change event, and a corresponding handler, and print out that the pin has changed, and the state in the handler to ensure it's working properly.

using RoboticsConnection.Serializer;
using RoboticsConnection.Serializer.Ids;
using RoboticsConnection.Serializer.Sensors;
using RoboticsConnection.Serializer.Components;
using RoboticsConnection.Serializer.Controllers;
using System;

namespace test
{
    class Program
    {
         static Serializer serializer;           
         static GpioPin pin0;
         static GpioPin pin1;
             
         static void Main(string[] args)
         {
              serializer = new Serializer();

              pin0 = new GpioPin(serializer);
              pin0.Pin = GpioPinId.Pin0;
              pin0.Set += new SerializerComponentEventHandler(pin0_Set);
              pin0.Cleared += new SerializerComponentEventHandler(pin0_Cleared);
              //pin0.Enabled = false;   // Set to false if you want to use as output

              serializer.Run();  // Or Serializer.PumpEvents() in a tight loop
                
              // Now, if you  apply +5V or GND to I/O lines 0 and/or 1,
              // you should see the events fire...
          }

          static void pin0_Set(SerializerComponent sender)
          {
              Console.WriteLine("Pin 0 Set");
          }

          static void pin0_Cleared(SerializerComponent sender)
          {
              Console.WriteLine("Pin 0 Cleared");
          }
     }
}

Let me test this, but something doesn't sound right.  It should have a VERY fast repsonse, even over BT.  Did you have any other non-serializer code that happens to be blocking on something for short times, or hogging cpu so that Serializer.PumpEvents() doesn't get called frequently enough?
