Looking at 6 such small resolvers for organizations ranging from 20 to 200 users, the memory usage of bind/named is between 200MB and 900MB. On the system with the largest memory usage: cd /var/named rndc dumpdb -all egrep -v '^( |'$'\t''|;)' named_dump.db | wc -l shows 83K lines, many of them for an internal rpz zone. Removing that, we have 25K lines left. Removing duplicate names (where we have multiple record types), we have 21K names. Note that those may have accumulated over much more than a day. The longest TTLs are around 600K seconds, mostly from names in amazonaws.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEAREKAAYFAlb8NrwACgkQL6j7milTFsGNXACdF6TNim5+pA7KebQOB7D0wOa3 2WEAninhTYLPMqCbCXXLEVrkJs3pIHxy =343c -----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
