One trickt that helped for me in some cases is, to set the value of
Periods/Buffer to 3. I have seen setups where 2048 F/P with 2 P/B was
unusable and 128 F/P with 3 P/B worked flawlessly.

At the other hand, using a properly  set up system with a
envy24-soundcard (Terratec EWX, MAudio) allows stable working without
need for much caution at 5.8 ms and it allows to lower the latency below
2ms by raising the samplerate.
