lol someone needs to open google and see how many people get way less lag with a good dns on cod.
A few out of millions tout this (clouded) solution; but, show me the proof... that the dns server change is the reason and not, maybe, a routing change, dns/other servers (speed, redundancy, capabilities, connections, etc.), bandwidth usage (capacity/congestion), or etc. are not the real cause/effect.
And, a single spot test is not proof... you will need to monitor the connection over time, not the initial connection itself.
Yes, it may help with the address lookup and one DNS server maybe better/faster/more thorough than another, but, it is not going to improve the connection you are using at the time you are using it.
A DNS lookup is only going to affect the original or updated address search.
You need to google and read and understand the complete process going on.
You know, it is hard to get someone to understand something when they won't accept the truth.
There is a lot more to the pipeline (from you to the destination) than what you see on the surface.
I have neither the patience nor time to explain it all, maybe someone else will.
My only advice to you would be; take classes, read on the subject, listen, and comprehend what information you gather.
You should not ask a question, then tell everyone who answers they are wrong.
You probably will find a few who will rub your back and tell you what you want to hear.
Now, I have found a decent paper on the subject and if you actually read it, it may help explain what you are seeing. Be sure to make note of "Redundancy - Many servers with the same answers".
