hi i have recently upgraded computers and i have moved to 64bit, with that i have updated-ed a lot of my old software including comodo dragon. I have recently noticed that most things that i download through comodo dragon are only downloading at 10 - 20 kbps where as every other browser seems to be fine, also the word comodo is not added to the dictionary so it seems to think that im spelling it wrong ;D
Did you check the option to use SecureDNS in Dragon only? If so, it’s possible that you aren’t being routed to the content server nearest you.
Is this a clean installation of CD? Or to rephrase it.Did you import stuff from your old CD installation?
DNS does not interfere with speed. Once the connection is established DNS played its role and is no longer an influence.
I agree with this answer totally. I have posted this prob too & mostly all of them gave this reply.
But still I would say somehow I too get slow downloads with Comodo DNS in CD & the global too i.e changing the DNS in the system.
For EX - AVG offline installtion file. Its 150 MB.
If I download the file with my ISP DNS then the download speed I get is app. 400 kbps & with Comodo DNS its app. 100 kbps. I have checked the difference many times with many different downloads & theres always the difference in the speed & the difference is huge. So now I have to stick with my ISP DNS.
I wanted to use comodo dns coz it gives security & now content filtering is coming too but I cant coz of the download speed prob.
You are correct that DNS does not affect your throughput.
However, since third party DNS services have not been capable of providing localization data, (up until now, more in a bit…) you have never been guaranteed to be routed to the CDN servers closest to you.
So, using your ISP’s DNS, you may be routed to a CDN sever that is within 50 miles of your location, whereas a third-party DNS resolver may route you to a server several hundred miles away. Chances are pretty good that the closest server is going to result in a quicker download because there are less hops required to get you there.
Currently though, this is changing. Google, OpenDNS, and apparently the version of SecureDNS in beta is capable of knowing your geographical location and is able to supply this to help ensure that you are being routed to the nearest CDN servers.
You mean DNS server and not CDN server I suppose.

Talking about number. Several hundred of miles would be from me to the UK. Ping times to the UK are pretty fast. Ping times to the US are definitely slower from here (The Netherlands).

No, I mean CDN server. If you’re going to download something, or use a service such as YouTube that utilizes CDN’s from various locations around the world to improve download speeds by giving users a more local download server.
It’s no mystery that the farther your download needs to travel, the slower it will become depending on net congestion and the route it takes to get to you. The closer the server you are downloading from, the better the chance is that you will have quicker download speeds. (of course, the closest server could still be the busiest…)
As stated above. An actual quicker download because you are closer to the CDN datacenter.
Yes, so what I’m saying is, using your ISP’s DNS, you’re likely to get connected to a CDN server on at least the same continent because your ISP knows where you are located. All bets are off when you’re using an external DNS service because until now, it hasn’t been possible for the external DNS to pass on your location. Instead of a server in the UK, it might route your download to the US. But with this new edns-client-subnet, a truncated IP is sent with the DNS request, allowing you to be localized.

The net result is less latency and faster downloads. Comodo is one of the participants in this project.
