I've not touched that code recently though, so this is possibly out of date information. Also, which version of BIND 9.x introduced the epoll() I am not certain of. That said, the single biggest problem in BIND 9 currently in terms of using all CPUs on a high-core machine is that all initial I/O is processed on a single core per UDP socket. Thus, you had 32 real cores in a server today and would use this beast for DNS, you'd not be happy unless you somehow spread this across multiple UDP listening sockets. We're working on this though. As with all things, we work on the things that are most important to our customers and users, so making your voice heard that this is important is helpful to us. Running code is always good too, as is a monetary donation for a development effort you want to see moving forward faster. - --Michael -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOC1eJAAoJEDRzoY2A7tzbOTYH+wZUawX9R+dH6weqxXlyTLL+ 48OtpAh/DHDyPGFCa7O3IDuYdvNr455oAoSzN4qSLV/gEAKsRCLC3mxa90Fit367 r4goLR4uC96DYMKWdUJzsruxqeyUcET1xbNRWiz+g5M40ZJf0YYpW4mIlGls+9UP lXyFiCAxESTmklYNrwTy++m4Hz8JjuV9FsbXzvlu0IyQR+qdbsZ3xYleHblawb1b Q57hpXvcmpxI4e7hRrj0Q2QdfZKk87+LXiErWbhaqui/hOw89PAlF7HR1J8vwLtj maBil2+UV3kSUtF3EVoFasuQKUTYWM14uqYA4Eu3RbHWVf4VJuZ1+gB3dhtbBh0= =7Qi6 -----END PGP SIGNATURE----- _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
