@ -598,12 +598,14 @@ overhead for the actual polling but can deliver many events at once.
By setting a higher I<io collect interval> you allow libev to spend more
time collecting I/O events, so you can handle more events per iteration,
at the cost of increasing latency. Timeouts (both C<ev_periodic> and
C<ev_timer>) will be not affected.
C<ev_timer>) will be not affected. Setting this to a non-null bvalue will
introduce an additional C<ev_sleep ()> call into most loop iterations.
Likewise, by setting a higher I<timeout collect interval> you allow libev
to spend more time collecting timeouts, at the expense of increased
latency (the watcher callback will be called later). C<ev_io> watchers
will not be affected.
will not be affected. Setting this to a non-null value will not introduce
any overhead in libev.
Many (busy) programs can usually benefit by setting the io collect
interval to a value near C<0.1> or so, which is often enough for
