On: Ad Blocking Extensions Tested for Performance

[huuu]

I'm not sure: isn't it faster to just refuse the request than directing it to localhost and waiting for a time out?

As long as you don't have a firewall blocking traffic to/from localhost, the TCP connection will be reset almost immediately (assuming you don't have an httpd running on port 80) so you won't have to wait for a timeout.

That's the point. We'd like to see which is faster.

localhost will RST the connection just fine, provided you don't have a webserver listening there.
