DNS or Domain name system is a system that keeps records of domain names and translates them into IP addresses. It’s like a phonebook of the internet and DNS lookup means that every time a user/visitor looks for a particular domain name, this request will be forwarded to the DNS server and returns with an IP address associated with that domain name. As a result, users or visitors can now see the site’s web pages. (techopedia)

Let’s take your website as an example, every time a user search your domain name, a DNS lookup process will take place and this DNS lookup process will be the responsibility of the browser, so before your user could see your web pages, it would take some time to load or until or until the DNS lookup completes. And based on the YSlow data, DNS lookup could take an average of 20 – 120 seconds for it to complete. (keycdn)

This process alone could highly affect your site’s load time.
