This is just a test to see how fast it can be with only two records in lua:
records["host.test.com"] = {domain_id = 11, name = "host.test.com", type =
"A", ttl = 120, content = "10.11.12.13"}
records["www.test.com"] = {domain_id = 11, name = "www.test.com", type =
"CNAME", ttl = 120, content = "host.test.com"}
PowerDNS was running with only one thread and all cache-values set to zero!
