Issue Details

After building my code into an executable I've noticed that it runs significantly slower than the code in my development system on the same computer. What can have caused this?  


When a built application is running slower than a code in a development system on the same computer, it's usually caused by the antivirus system reacting to an unknown executable being executed.   

To fix this NI recommends talking to your local IT department, to add an exception for the application.
