[Dnsmasq-discuss] Huge hosts file and CPU usage

[Mike Leong]

Hi,

I have a blacklist of 1.5 million entries loaded into dnsmasq via "address"
definitions.  eg:

address="/bad-site.com/192.168.5.1"

The 1.5 million entries are a list of porn/warze sites collected from
various blacklists.

According to top, dnsmasq uses about 200MB of RAM w/ that list loaded.

I'm noticing high CPU usage w/ that blacklist.  (spikes to about 80% on an
i7)

dnsmasq version: 2.62-3+deb7u3  (from debian wheezy)

Are there any tuning (compiler options, code changes) what would reduce the
CPU usage?

I also tried using addn-hosts format but CPU usage was the same.

thx
mike
