That’s like the most trivial of theories one can test for.

Save response time every minute

while true; do /usr/bin/time -f "%e `date`" dig '@1.1.1.1' +noall programming.dev &>>/tmp/dns_clf_perf.txt; sleep 60; done

Then after a while (maybe a couple of days), check the worst numbers:

sort -n /tmp/dns_clf_perf.txt |tail

Run the same script with a different DNS server at the same time, and compare numbers.

Dates included in case there are any patterns regarding the time of day/week.

A reminder that the Servo project has resumed active development since the start of 2023, and is making good progress every month.

If you’re looking for a serious in-progress effort to create a new open, safe, performant, independent, and fully-featured web engine, that’s the one you should be keeping an eye on.

It won’t be easy trying to catch up to continuously evolving and changing web standards, but that’s the only effort with a chance.
