No matter what, what gets you the best performance is what you should choose to do. BIND 9 does not currently benefit as much from more cores, but does from more powerful cores. I suspect this is what is happening in your tests. The 4 core machine is able to be fully utilized, and each core is faster. In the 8 core machine, you are not only doubling the amount of data needed to be moved around in some cases, you are lowering the core speed. If BIND uses perhaps 6 of the cores, with the typical 64-bit overhead of more data and more effort on the system, you are losing performance. Also, like mentioned by several here, you are not using identical machines. When you benchmark and compare results, you want to minimize the differences or at least account for them. Your machine is not just made of CPUs, it has memory (which may vary in speed), network cards and the drivers (which may be better or worse depending in the card and drivers), and motherboard chipsets in use. There are just too many variables to account for in your comparison that we cannot really help with. Thus, the only answer that is ultimately important to you is, on this new hardware, how can I make BIND 9 run fastest? If that turns out to be a 32-bit OS or a 32-bit named binary, that's your answer. - --Michael -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOC2bZAAoJEDRzoY2A7tzbkf8H/iIOCnEUfz8p6AtTBzuxcRag z5R4f4C9vVd2MtqvYbN4BxrLz8dfqlgYM4ZAtIB7HyQnFnkeNuxIiqc1PDec6866 mpk/COSF+RP+mzMqenEbWcYOPl/giVq/0qFL+oqiD9Fq4PQCltsgCwMSf65fLdgH CoutRsM8AAO3cJ6N80PIlAMe0kocP6K/MBGJyaJznKhZR/TusKCdRP9cg9xc9h51 Y6XlflaOE6EKXq9pv49JupUxSN6Fk5pVJ+jsBmr6wLroQIZpVZRK9Zm2idbvtrC5 L8EaeDgeYNJRCNglOT5kwYydAt/g3SvGkgm9Q1zNk+HqX18EeNTNqZqK31yETBo= =ZSz9 -----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
