high resolution timers and timer interrupt thrashing

Hi All, With CONFIG_HIGH_RES_TIMERS configured and a whole lot of timer_create with interval of less than jiffy (i.e., few nano seconds) we are bound to get timer interrupts less than a jiffy because set_next_event will configure for expires less than jiffy. This means we are thrashing the system with more timer interrupts, perhaps to extent of almost every clock tick, is my understanding correct? Given this is it not dangerous to configure CONFIG_HIGH_RES_TIMERS Please give your thoughts Thanks, Sudharsan
