1) Geographical/provider closeness (there is a root name server at an
exchange point connected to the network of my Internet access provider
so, obviously, this root name server replies faster).

2) Speed of the software (nsd, used by K-root, is much, much faster
than BIND)

% qtest 'SOA .' `dig +short NS .`
3 202.12.27.33#53(202.12.27.33)

(202.12.27.33 is M-root, qtest is attached.)
