I also replace 127.0.0.1 with 0.0.0.0 and duplicate each entry to have it for IPV6 as well, as in this script except I don't do the iptables rules: https://gist.github.com/teffalump/7227752
I have a netbook, so always want to keep an eye out on performance.
I wonder if there's a GUI application which enables these hosts sources to be tweaked, searched, whitelisted etc
Hostsman (http://www.abelhadigital.com/hostsman) on windows is the my choice of a frontend for hosts management. It's free but not open source.
The solution is to feed the data to a DNS caching resolver such as unbound or dnsmasq, as I have explained in reply to UserRights.
Answering here also to point out I originally implemented this on a 5y old netbook (Atom CPU, 1GB RAM) because I tend to have a lot of tabs open in firefox, and ABP's memory usage quickly becomes noticeable, and then comes the swapping. Running unbound+nginx scales remarquably well, without hogging too much memory at startup. (Sorry, I don't have access to the netbook right now to report real numbers).
