[Pdns-users] Performance optimizations in recursor

[Miguel Miranda]

Hello to all, i have followed to the letter the performance tunning
document, this is my recursor.conf:

setuid=pdns-recursor
setgid=pdns-recursor
daemon=yes
dont-query=127.0.0.0/8
local-address=127.0.0.1
log-common-errors=no
loglevel=4
max-cache-entries=4000000
max-negative-ttl=30
max-packetcache-entries=4000000
packetcache-servfail-ttl=30
server-down-max-fails=16
quiet=yes
threads=4
security-poll-suffix=
dnssec=off

This is running on 2 x quad core 32GB RAM pdns-recursor 4 alpha. As it is
indicated by the document as i high packet cache hit rate 87% and low cache
hit rate 16%. Seeing this numbers, should i increase the
max-packetcache-entries
value or to lower the max-cache-entries to get better performace? Or am i
doing good if i keep this values?
