An article discussed on HN's front page (news.ycombinator.com/item?id=216048…) has the following footnote (see pic).
Browsers have their own DNS cache, and extensions can create their own cache so as to avoid having to DNS-lookup every network request. The statement ignores this fact. pic.twitter.com/HdfZkfztQu

My expectation is that *when* uBO needs to make a DNS lookup, the browser will cache the result and thus will reuse the result should uBO not block the network request.
Thus I do not expect uBO's own DNS lookup to cause extraneous latency as opposed to what the article suggests.
