Here is some info regarding your questions:-
The portion of unbound.conf pertaining to the "HowTo Optimise":
# Optimise settings
num-threads: 112
#
msg-cache-slabs: 64
rrset-cache-slabs: 64
infra-cache-slabs: 64
key-cache-slabs: 64
rrset-cache-size: 1024m
msg-cache-size: 512m
infra-cache-numhosts: 100000
#
# Larger socket buffer
# For Solaris 11 set the following UDP parameter 1st:
# 'ipadm set-prop -p max_buf=8388608 udp'
so-rcvbuf: 8m
so-sndbuf: 8m
#
outgoing-range: 8192
num-queries-per-thread: 4096
Not sure if the following have any affect:
incoming-num-tcp: 128
outgoing-num-tcp: 256
The summary from "prstat" command:
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
12007 dnsadmin 6376M 6374M cpu56 33 0 336:22:17 11% unbound/112
Total: 47 processes, 862 lwps, load averages: 27.53, 27.50, 27.57
The upstream connections is ok, we have a BIND9 recursive DNS in the
same segment running in excess of 5200 qps with a load average of
between 7 and 8, summary from "prstat" below
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
1469 root 1684M 1680M cpu8 52 0 2871:14:3 21% named/35
Total: 34 processes, 203 lwps, load averages: 7.54, 7.52, 7.46
These are production recursive DNS's taking a mix load from ADSL users
and, yes, DNSSec is enabled. Disabled IPv6 in the config:
do-ip6: no

Zitat von Jaco Lesch <[email protected]>:
Does anybody have some additional performance tuning tips for
Unbound, specificityon Solaris 11?
I have followed the recommended settings in the "HowTo Optimise", but
still seem to hit a ceiling of +/- 3600 max queries a second.On top
of that the platform/OS do become a bit sluggish when logging in via
SSH.
Our install details:
OS: Solaris 11
CPU: SPARC T3
Unbound ver: 1.4.18-2 (64-bit)
LDNS ver: 1.6.15 (64-bit)
Libevent ver: 2.0.20 (64-bit)
Hello
you should clearify the following questions
Which part of the "HowTo Optimise" do you use and how?
What is the load on your system as of CPU power used?
Have you checked the upstream connection or forwarders used?
Do you use DNSSEC? What kind of data do you use for testing?
Without this no one will be able to tell why your system max out at
3600qps.
Regards
Andreas
