Using the adblock set of scripts to block malware and porn sites. The
porn sites list is 800,000 entries, about 10x the number of sites
adblock normally uses. With the full list of malware and porn domains
loaded, dnsmasq takes 115M of memory and normally sits around 50% CPU
usage with moderate browsing usage. CPU and RAM usage isn't really a
problem other than lookups are slow now. Platform is cc 15.05.1 r49389
on banana pi r1.
The adblock script takes the different lists, creates files in
/tmp/dnsmasq.d/ entries looking like
local=/domainnottogoto.com/ one entry per line. The goal is to return
NXDOMAIN to entries in the lists. Lists are sorted and with unique entries.
I've tried increasing the cachesize to 10,000 but that made no change.
Tried neg-ttl=3600 with default negative caching enabled with no change.
Are there dnsmasq setting that will improve the performance? or should
it be configured differently to achieve this goal?
Perhaps unbound would be better suited?
Cheers
Derek
