Netduino runs faster when debugging

I've reported this problem to Microsoft:

They are currently working on fixing a number of issues, hopefully this one will also be addressed.

..just an observation which I dont understand!

 

I have a simple program running at the moment that just reads a sensor and writes the result to a serial port...

every time it goes around the loop it toggles between two LEDs

 

while (true)

{

ToggleTwoLEDs();

ReadSensor();

WriteResultToSerialPort();

}

 

while running in visual studio the loop runs very quickly, when i stop debugging the LEDs toggling reduces to about quarter the speed (according to my eyes)..

 

what is going on?

OK, all fixed now thanks..

 

I just replaced all instances of Debug.Print with a function called "DebugPrint", then i have a global bool i can toggle to compile with the debug output turned off.. now running at full speed:

 

static bool inDebug = false;
 
        public static void DebugPrint(string output)
        {
            if (inDebug)            
                Debug.Print(output);
        }

Or just select "Release" configuration. It will auto remove the Debug when building the app.
