6. Speed

Result: During the checks in the previous steps, multiple DNS requests were executed to the name servers responsible for the domain name. Average response time of the name servers is 67.36ms.
Recommendation: The name servers respond slow. Try moving to an Anycast DNS service in order to speed up the resolution of the domain name and first page load of the web site.
