Delay when calling SKLabelNode?

Question

I have a problem with a slight delay (lag) when switching from one SKSceneto another. Commenting on various bits of the code, I narrowed it down to SKLabelNode, I assume that it is loading / caching the font when called, which leads to a slight delay / stutter when specifying a new one SKScene.

Has anyone else noticed this, it is less obvious when you just use a single one SKScene(for example, the default template), since the slowdown is simply lost with the usual delay in starting. Does anyone know a way around this, is there a way to preload the font? I think I can download the font on UIViewControllerstartup and see if I can access it using SKSceneany idea?

-(id)initWithSize:(CGSize)size {
    if (self = [super initWithSize:size]) {
        [self setScore:0];

        [self setBackgroundColor:[SKColor blackColor]];
        SKLabelNode *labelNode = [SKLabelNode labelNodeWithFontNamed:@"System"];
        [labelNode setText:@"00000"];
        [labelNode setFontSize:20.0];
        [labelNode setPosition:CGPointMake(CGRectGetMidX(self.frame),500)];
        [labelNode setName:@"SCORE"];
        [labelNode setAlpha:1.0];
        [self addChild:labelNode];
        [self setScoreLabel:labelNode];
        ...
