Varnish rocks! For the yearly 24urenloop event we use a drupal website. Last year we used three servers to host the website and it still was slow. This year we use varnish as a reverse proxy in front of a single server serving Drupal, and this server is less performant the one used last year. We get a lot more request and the load on the server is less than 0.3 All static content is cached for 600s, all live updates are cached for 10s, all the rest is cache 60s. We have a hit ratio of about 90%.
