The problem isn't completely solved, though. https://www.reddit.com/r/Windows10/comments/401h2o/hosts_file_update_is_extremely_slow/ https://www.reddit.com/r/W

  Isn't the O(n^2) operation described in that thread happening only when the hosts file gets updated, and not with every DNS lookup? I would imagine even sequentially searching a local list of 350,000 entries, like the post describes, would still be extremely fast in the context of loading a web page. But, that said, there can be a huge difference between how one might think things should work and what actually happens.
