So I have a web-server on my localhost under `app.local` virtual server in Nginx config. When I make requests to it I notice that it takes cca. 5 seconds per requests. Looks pretty much as a timeout for DNS resolution.
The problem is known and there are several solution in the Internet. But only this helped me:
So this trick is to specify IPv6 address too. And put hosts one per line -- hosts after the first one are ignored (a bug?).
