[tor-relays] Boosting throughput with own DNS resolvers

Recently I noticed my Tor Exit nodes were showing nameserver errors in
the tor log and I decided to set up two private DNS resolvers
(pdns-recursor). Since I use those I have seen an increase of traffic
throughput on my Exit nodes to approx. 150%. I feel I am finally
utilizing the resources available.

All bigger Tor relay operators will probably already do it this way,
but as I myself have long been using Google DNS or other privacy-aware
DNS resolvers on my nodes I just wanted to throw this out in the open.

How many of you are already using private DNS resolvers for your
nodes? Any feedback/ideas about this?
