Overhead associated with OutputDebugString in release build

Question

Is there a significant overhead associated with calling OutputDebugString in release build?

Answer 1

Why not measure it yourself? Compile the following code, run it & time it. Then remove the call to OutputDebugString, recompile and rerun. Should take abut three minutes of you time.

   #include 

    int main() {
        const int COUNT = 1000000;
        int z = 0;    
        for ( unsigned int i = 0; i < COUNT; i++ ) {
            z += i;
            OutputDebugString( "foo" );
        }
        return z;
    }
