DNS performance Help when query log is off -- which default parameters will impact the DNS performance

[Paul Kosinski]

Google search for "man named" turns up:

  https://ftp.isc.org/isc/bind9/cur/9.9/doc/arm/man.named.html

which says (among more details):

  named [-4] [-6] [-c config-file] [-d debug-level] [-E engine-name] [-f]
    [-g] [-M option] [-m flag] [-n #cpus] [-p port] [-s] [-S #max-socks]
    [-t directory] [-U #listeners] [-u user] [-v] [-V] [-x cache-file]

For more explanation, look at:
