It's nothing to do with the UI really. You're doing well if you get less
than 40ms out of a standard sound card, but if you use a good external
audio interface you could see as low as 5ms.

Above 15-20ms is when the ear starts to hear two distinct sounds, although
it can be uncomfortable to sing and monitor with a latency of >10ms.

So I would say a good latency would be <10ms. But good luck getting there :)
