198 ;;Quote: used soft-timers for rate-based clocking of TCP and network polling to avoid interrupts; 25% faster Web server
200 ;;Quote: hardware timer interrupts are expensive; context switch, highest priority, poor cache locality
201 ;;Quote: use efficient, trigger states and timing wheels for soft timers; end of system call, end of exception handler, end of interrupt handler, idle loop
220 ;;Quote: on-chip timer interrupts are scheduled and canceled at the cost of a register access
220+;;Quote: back up soft timers with on-chip timer interrupts; low overhead
