Background I have been doing a fair bit of scale testing for York University Digital Library over the last couple weeks. Most of it has been focused on horizontal scaling of the traditional Islandora stack (Drupal, Fedora Commons, FedoraGSearch, Solr, and aDORe-Djtatoka). The stack is traditionally run with Apache2 in front of it, and it reverse proxies parts of the stack that are Tomcat webapps. I was curious if the stack would work with nginx, and if I would get any noticeable improvements by just switching from Apache2 to nginx.
