well, the so called "tickless" option is about omitting kernel

setting the HZ=1000 is mostly desirable for the default ALSA MIDI system
timers to have a better resolution than the Linus' default (HZ=250).

i'm just wondering why you'd bother to set HZ when the preferred configuration is
NO_HZ .. ?
