Hi Jiankang,
What reason do you have to think that response latency from root servers
has any measurable impact on end-user experience?
Queries to root servers from individual clients are sent very
infrequently, in my experience; the TTLs are not short. The probability
that any client of a real-world resolver gets a delayed response because
of latency between the resolver and a root server seems vanishingly
small.

Dear all,
I submit a draft about Decreasing Fetch time of DNS Root Data.
Many DNS recursive resolvers have long round trip times to the DNS
root server. It has been an obstacle to increse the performance of
DNS query. In order to decrease fetch time of DNS root data, this
document proposes a new mechanism by improving the mechanism of root
data cacheing.
Pls kindly help to review it and give the comments.
I would also like to apply 10 minutes slot to introduce this idea
in the next IETF meeting
thanks a lot.

Abstract:
Many DNS recursive resolvers have long round trip times to the DNS
root server. It has been an obstacle to increse the performance of
DNS query. In order to decrease fetch time of DNS root data, this
document proposes a new mechanism by improving the mechanism of root
data cacheing.
