I would like to know what are the steps or ways to improve ping time & dns timing?
Ping #1: 470ms [TTL=49]
Ping #2: 389ms [TTL=49]
Ping #3: 383ms [TTL=49]
Ping #4: 350ms [TTL=49]

DNS Timing
ns1: 367ms.
ns2: 373ms.

Currently, my server is hosted in asia.
Is it possible to improve the time by obtaining ns3 & ns4 using IPs based in US or Europe?

Please Advice.

Thanks a lot! Guys.
