Hi,
I am deploying a couple of unbound hosts on FreeBSD 7.2 Stable and was
wondering if there are any OS tweaks you would recommend to get the best
performance. Will be doing around 10000 qps at peak times.
Boxes have 4 Gigs Memory and unbound 1.3.4 is being built from ports with
both LIBEVENT and THREADS selected.
unbound.conf is as follows
server:
# use all CPUs
num-threads: 2
# power of 2 close to num-threads
msg-cache-slabs: 2
rrset-cache-slabs: 2
infra-cache-slabs: 2
key-cache-slabs: 2
outgoing-range: 4096
num-queries-per-thread: 4096
# more cache memory, rrset=msg*2
rrset-cache-size: 512m
msg-cache-size: 256m
verbosity: 1
statistics-interval: 0
extended-statistics: yes
statistics-cumulative: no
interface: 127.0.0.1
interface: x.x.x.x
outgoing-interface: x.x.x.x
port: 53
do-ip6: no
access-control: 0.0.0.0/0 allow_snoop
access-control: 127.0.0.1 allow_snoop
chroot: ""
username: "unbound"
directory: "/usr/local/etc/unbound"
logfile: "/var/log/unbound/unbound.log"
log-time-ascii: yes
pidfile: "/var/run/unbound.pid"
root-hints: "/usr/local/etc/unbound/root.servers"
hide-identity: yes
hide-version: yes
harden-glue: yes
# Remote control config section.
remote-control:
# Enable remote control with unbound-control.
control-enable: yes
# what interfaces are listened to for remote control.
control-interface: 127.0.0.1
Thanks for your time
Cheers
Gareth
