Is there a configuration option to tune epoll timeout in lighttpd?
I'm developing an embedded Linux (2.6) device, with lighttpd 1.4.30. And I'm observing the following issue: even when the system is idle and there are no web clients connected, the lighttpd wakes up every second (see below).
/# cat /proc/timer_stats
Timer Stats Version: v0.2
Sample period: 6.382 s
15, 137 alt-ecm hrtimer_start_range_ns (hrtimer_wakeup)
23, 5 events/0 uectl_readerwork (delayed_work_timer_fn)
10, 380 db_probe hrtimer_start_range_ns (hrtimer_wakeup)
3, 121 atswitch hrtimer_start_range_ns (posix_timer_fn)
6, 380 db_probe hrtimer_start (timerfd_tmrproc)
6, 226 lighttpd sys_epoll_wait (process_timeout)
the goal is to minimize number of wakeups from idle in the system Thanks in advance!
