    check here.
    the high-res timers feature (CONFIG_HIGH_RES_TIMERS) enables POSIX
    timers and nanosleep() to be as accurate as the hardware allows (around
    1usec on typical hardware). this feature is transparent - if enabled it
    just makes these timers much more accurate than the current HZ
    resolution. It is based on the Generic Time Of Day patchset from John
    Stultz and it in essence finishes what we started with the
    kernel/hrtimers.c code in 2.6.16.
    It is amazing what you can accomplish if you do not care who gets the credit.
