Apache and Nginx, same as Firefox and Chrome.

When I was at Linuxcare, I had the static assets moved over to a different server with Boa, since the main Apache server had a massive mod_perl memory footprint. It speeded things up and freed up a lot of memory. And this was 10 years ago...
The Apache advantage has always been that it did (a lot) more than just spit out static files quickly. Perhaps nginx or something else will take its place, but it certainly won't be merely a question of event-based servers being faster with static files. We've known that for many years.
