    In this section the complexities of (many of) the algorithms used inside +libev will be explained. For complexity discussions about backends see the +documentation for ev_default_init.

    Starting and stopping timer/periodic watchers: O(log skipped_other_timers)
    +
    Changing timer/periodic watchers (by autorepeat, again): O(log skipped_other_timers)
    +
    Starting io/check/prepare/idle/signal/child watchers: O(1)
    +
    Stopping check/prepare/idle watchers: O(1)
    +
    Stopping an io/signal/child watcher: O(number_of_watchers_for_this_(fd/signal/pid % 16))
    +
    Finding the next timer per loop iteration: O(1)

    Each change on a file descriptor per loop iteration: O(number_of_watchers_for_this_fd)
    +
    Activating one watcher: O(1)
