Sync (ie, only when the ring is empty) which kills performance.

I actually think it's doing the full sync each time and not the lazy I'll have to go remember what I saw when I On 22 October 2015 at 11:24, Luigi Rizzo wrote: If I do ioctl(fd, NIOCTXSYNC, NULL) before kevent - packets transmited.Īlso, can you look in this thread about VLAN processing? If I do ioctl(fd, NIOCRXSYNC, NULL) after kevent I am see received packets in rxring, but nothing transmited. I am register file descriptor in kevent withĮV_SET(ke+used, thr->outside.fd, EVFILT_READ, EV_ADD | EV_ENABLE | EV_CLEAR, 0, 0, &thr->outside) Īfter got event in kevent(kq, NULL, 0, ke, max_event, NULL) I am don't see anything in rxring. > is an implicit sync, and there is another one when an event When the file descriptor is registered there > On Thu, at 11:12 AM, Adrian Chadd wrote: Is an implicit sync, and there is another one when an event kqueue() doesn't do the implicit sync like poll() does it'sĪctually not.
