DNS performance redux | StyleFeeder Tech Blog. It’s no secret that we have spent a lot of time on performance at StyleFeeder, mainly because it’s one of those things that you end up addressing when you’re scaling, but also because it can yield very tangible results for user metrics. It turns out that people really like using fast websites. Go figure. About a month or two ago, we looked in more detail at the chain of events that occurs when a browser hits our site to see if there were any possibilities for making things better. This is increasingly hard for us to do given that we’re already serving stuff up pretty quickly, especially when you consider the size of our dataset and the sparse nature of our requests. Anyway, we noticed some room to improve our DNS numbers, which I mentioned in a post last April. So, I ran some tests using Pingdom for the entire month of June, 2009 that compared Dynect, Enom, DNSMadeEasy and Jerky.
Enom’s DNS service is included with their domain registration service while DNSMadeEasy costs money. Java DNS Lookups | mugfu. WeoCEO - Easy to Use. EC2 Love.

How to Compare Hosted DNS Providers (with Data!) - DNS. My colleagues & I run a popular website and are constantly concerned with scaling and performance. Until last week, we had been running our own DNS servers (BIND) on Amazon EC2 instances.
We use Pingdom to monitor many functions of our servers, including DNS. What we saw was a resonable average resolution time of about 130ms, but frequent outliers higher than 500ms! The thought of a half-second penalty to the load time for first time visitors is not appealing. So we started to dig into the problem. DNS, or Domain Name System, is one of the core pieces of infrastructure on the Internet. If the DNS server your browser contacted does not have the IP address cached, then it will attempt to locate and contact an "authoritative name server". Site operators can either run these authoritative name servers themselves, or outsource it to another company. Popular websites get hundreds of DNS queries per second (QPS), often from all over the world. List with more hosted DNS services » DNS Reviews - Managed DNS Provider Reviews and Information.
