COMODO SECURE DNS encounters excessive RTO

Agree :-TU

DNS RESOLVER is more applicable on those who experienced intermittent connection and low throughput broadband platform. In telecom industry, the LOWER the PING, the Better connection. I remember talking to a HUAWEI, MOTOROLA and SAMSUNG Telecom (WiMAX) Engineers when we talk about congestion’s and quality base on transmission type, they all do not believed on a 2nd party dns hence, throughput and less routing is a key for a fast internet. I trust comodo dns for a safer browsing but what I learned through school and almost everyday actual troubleshooting in broadband outages from base stations where I work, I firmly believed that lower ping or route and high transmission speed (Tx/Rx) makes your internet faster

just run dns benchmark and you will find the fatest ones near you. GRC's | DNS Nameserver Performance Benchmark  

That’s a useful utility by Gibson. An alternative is namebench - Open-source DNS Benchmark Utility It’s interesting to compare the results.

Well I’d like to make a remark to this, that does not always have to be true, a server can have an excellent ping response but if it is overloaded or having other issues causing TCP to scale the window size to zero, or cause way to many retransmits it won’t perform for a single bit, even though icmp might show good response times. It highly depends on the situation, it’s better not to assume everything is ok based only on a ping test.

I will give and example of a small MAN(network).

Imagine that you have 3 routers which one have 2 connections in a Serial cable. Using Routing protocols I will give an example of RIP v2 this protocol will select the way where the packets will flow, it will see the ping of each node the MTU the clock rate of each port etc. It’s not only based on one factor(ping).

SERVERS now a days (Specially HUAWEI CX Links for 3G) has a LOAD SHARING capabilities, therefor, OVERLOADED or CONGESTION in NOT possible unless, yor ISP’s DNS is using a traditional DNS methods.
LOAD SHARING dramatically improves ping and less congestion.

Yes but in that case your talking about the transport-level of the bit’s and bites.
I was more talking about web/file/ftp-servers etc, tcp layer-4 assuming a ‘perfect’ transport layer ;D

True if we are talking about the OSI model. :smiley:

Another COMODO DNS TRO’s…

I cannot connect to the Internet via FF / OPERA / GCHROME and SAFARI…
that’s why I disable COMODO DNS in my Router.

This is a great utility. But unfortunately for Comodo it has shown me that consistently faster is Open DNS so I have returned to use them again. I think the potential downside is lack of malware detection by OpenDNS but I think Malwarebytes Pro does a very good job of blocking bad IPs
