Benchmarking on different machine types, even if they are identical speed, can be affected by any number of issues: ethernet card type, motherboard chipset, etc. Even features chosen on an identical chipset. For true comparison, one must run the 32-bit OS on the same hardware (not just "similar" hardware) to do a direct comparison. That said, more is not always better. 64-bit means it can move more memory around faster in certain circumstances, and it can address more than 4 GB without pulling special hardware tricks. That said, it MUST move around double the memory in certain operations, like pointers. BIND 9 uses a fair number of pointers, so often times the overhead increases faster than the benefit of a larger accessible memory area. - --Michael -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOC0ErAAoJEDRzoY2A7tzb+sgH/2svm6VPTa8OTm6L3H+Rq0QY 5pHQsT55GoclIZ+ttTQBouz8bla4QIJ53Cwjpw1bnBFrH6LEIR0vWDalBA5RUmX/ 7ZVqShxhvI2MfpYaramFJEjocDMcDxxt4mmFk+StvqATaENJSaqfXxpXHpqViDoK Et5a+npBaHfqPCyVWKO3VUlgSMhqFo6xIUSGhuXl7spe65zPEBfat5/Kea8S+puS wynsW+M7/Steqh5yLOdN9oD/wWQNSqOXSRZFpGliZNuFyrk90dWB0T+cyXMki7Jd Ls+fAyE7Z0jKPJIE0ttgJ0ditSXOFzW4oQmMfxd4eN+WzTDRXAF/zJUcsvGCMos= =IwZR -----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
