More than 50% of the Alexa top 1,000 companies use “plain” DNS (internal vanilla service or basic service from their ISP). Why? DNS is often overlooked until it breaks down. Let’s face it, we take fast and reliable DNS resolution for granted, and focus all our efforts on optimizing what happens after a connection to the server is established, but in many cases it spells SPOF.
Even when everything works well, DNS has a significant impact on user experience. An average page uses 15 domains (per httparchive.org), meaning 15 DNS resolutions, with each often taking up to 50 ms, and much more on mobile networks. Additional factors like high latency mobile networks, heavy use of CNAMEs and low-powered home routers make this problem worse. Implementing a fast and efficient DNS service, and understanding how DNS works on different browsers and operating systems and devices becomes critical for overall web performance.In this session you can learn:
To finish this session I will share analysis and best practices on newer and less discussed protocols like IPv6, DNSSEC and the impact of open resolvers. Even though these are supported by a small portion of the user-base, they may have significant impact on performance of the rest of the user-base and are growing on their own, and calls for additional consideration.
