Latencies are more deterministic with the RT kernel but slightly higher. You'll have better luck with a vanilla kernel running your app in run level 4. And then even better luck running on an SMP machine isolating your process and IRQ to a single processor. And stay away from the VGA console. You have better luck with faster hardware too.
