Last time I put a large list of blocked domains in my /etc/hosts file, it was causing non-trivial amount of delay (hundreds of ms) to every dns lookup. I guess hosts file is not designed to be scalable. I ended up running a local dns server (which able to use those blocked domains list without noticeable performance hit). These day I just use pi-hole running on a spare raspberry pi.
