Description:

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.
