This system's nameserver is 100% reliable.
DNS reliability is extremely important, since lookup requests that are dropped and ignored by nameservers cause significant delays in Internet access while the querying system waits for a reply. The system is then finally forced to reissue the query to the same or to backup nameservers. While your system is patiently waiting for a reply, you are impatiently waiting to get on with your Internet access.
During this benchmark test, the system's nameserver tested returned a reply for every request sent. It doesn't get any better than that. Very nice.
System nameserver is faster than ALL public alternatives.
The DNS resolver your system is using is responding faster than any of the 100% reliable publicly available alternative DNS nameservers this benchmark utility just tested. Therefore, there would be no performance benefit from switching to any of those publicly available nameservers. However, since you only have a single system nameserver configured, it might be useful to use some of the fastest public nameservers as backups if that's possible in your situation. Please also note that this best performance appraisal assumes that this system's nameserver is 100% reliable. See the next item below for an appraisal of your nameserver's reliability.
