timer_resolution

Reduces timer resolution in worker processes, thus reducing the number of gettimeofday() system calls made. By default, gettimeofday() is called each time a kernel event is received. With reduced resolution, gettimeofday() is only called once per specified interval.

Example:

timer_resolution 100ms;

Internal implementation of the interval depends on the method used:

• the EVFILT_TIMER filter if kqueue is used;
• timer_create() if eventport is used;
• setitimer() otherwise.
