fast BIND-style zonefile parser on top of Net::DNS
The Net::DNS::ZoneFile::Fast module provides an ability to parse zone files that BIND8 and BIND9 use, fast. Currently it provides a single function, parse(), which returns a reference to an array of traditional Net::DNS::RR objects, so that no new API has to be learned in order to manipulate zone records. . Great care was taken to ensure that parse() does its job as fast as possible, so it is interesting to use this module to parse huge zones. As an example datapoint, it takes less than 5 seconds to parse a 2.2 MB zone with about 72000 records on an Athlon XP 2600+ box.
