Right, however Ruby 2.6+ also has USE_THREAD_CACHE enabled to reuse threads. For applications which already uses short-lived (Ruby) threads; this can even be a win because reusing Ruby threads can improve locality. I prefer sticking to resolve.rb. c-ares <https://c-ares.haxx.se/> may be a another option if resolve.rb isn't fast enough. getaddrinfo_a(3) is the worst option IMHO.
