See these two test here below.
TEST1: the dnsmasq.adblockFULL contains about 15.9K CNAME records. I'm
generating the wanted dnsmasq.adblock file with an increased number of
records. The test is essentially parsing the file and benchmarking them.
As you can see there's something happening after 3000/4000 records as
the time required is not linear.

TEST2: In this second test the adblock is defined using address= (so A
records):
root@sparrow:/tmp/etc# wc -l /etc/dnsmasq.adblock
15966 /etc/dnsmasq.adblock
root@sparrow:/tmp/etc# time dnsmasq --test
dnsmasq: syntax check OK.
