Apparently, you never wrote any code which does polling without
latency...

The key is to know when data is available. This requires an adaptive
algorithm in setting up a wake-up timer, nothing more complicated.
After 5-6 cycles, you get the timer tuned-up, and run with minimal
overhead and no latency.

Hope this helps,
