You've verified this?  That they both record the same resolver
information. Or are you assuming this?  

Right after boot what does 'time host www.example.com' say?  [yes, you
can lookup "www.example.com" - please test with that and *not* with the
domain of your favorite social media or search site].

Also are you getting a routeable [2001:/8] IPv6 address on your network
interface?  If so, does IPv6 actually work?

If you disable IPv6 does it get faster?  [ set
net.ipv6.conf.all.disable_ipv6 = 1 in /etc/sysctl.conf and reboot].

>ss?  Also, I checked out the url and did not readily see mention of
'ss'.
