Hi my nickname lamoura.
Guys, help me please.
I have two servers :
1º - 8 cores, 16 gb ram
2º - 16 cores, 16 gb ram
What best values for the options below?
# some optimisation options.
server:
# use all CPUs
num-threads: <number of cores>
# power of 2 close to num-threads
msg-cache-slabs: <same>
rrset-cache-slabs: <same>
infra-cache-slabs: <same>
key-cache-slabs: <same>
# more cache memory, rrset=msg*2
rrset-cache-size: 100m
msg-cache-size: 50m
# more outgoing connections
# depends on number of cores: 1024/cores - 50
outgoing-range: 950
# Larger socket buffer. OS may need config.
so-rcvbuf: 4m
so-sndbuf: 4m
Hello
i guess you have already read
http://www.unbound.net/documentation/howto_optimise.html. The question
remain what your servers are used for. If you use them as caching
resolver for a larger number of clients you should use a libevent
enabled version of unbound and raise the outgoing-range and
num-queries-per-thread.

Andreas
