Hi,
I try to test unbound with dnsperf.
My old bind server on proxmox vm results e1000 driver 4G ram 4 virtual CPUs:
Statistics:
Queries sent: 12735
Queries completed: 12649 (99.32%)
Queries lost: 86 (0.68%)
Response codes: NOERROR 9192 (72.67%), SERVFAIL 119 (0.94%), NXDOMAIN 3338 (26.39%)
Average packet size: request 38, response 222
Run time (s): 14.771516
Queries per second: 856.310212
Average Latency (s): 0.054782 (min 0.000427, max 3.399655)
Latency StdDev (s): 0.145675
Where unbound has worse results on bare metal hardware (I have test server):
Statistics:
Queries sent: 4718
Queries completed: 4694 (99.49%)
Queries lost: 24 (0.51%)
Response codes: NOERROR 3384 (72.09%), SERVFAIL 41 (0.87%), NXDOMAIN 1269 (27.03%)
Average packet size: request 38, response 93
Run time (s): 13.592185
Queries per second: 345.345506
Average Latency (s): 0.201078 (min 0.000199, max 4.933770)
Latency StdDev (s): 0.345073
I try to use guide https://nlnetlabs.nl/documentation/unbound/howto-optimise/ after ершы settings performance worsened. (
Is there any guides to tune system for DNS perfomance?
I see 4 threads:
unbound-control status
version: 1.6.6
verbosity: 1
threads: 4
modules: 3 [ ipsecmod validator iterator ]
uptime: 1519 seconds
options: reuseport control(ssl)
unbound (pid 10732) is running…
Because CPU count is 4.
lscpu
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Thread(s) per core: 1
Core(s) per socket: 4
Socket(s): 1
NUMA node(s): 1
but htop shows only two unbound -d instances.
Thanks in advance.
