Self-notes...after spending a few hours researching and benchmarking various configurations. Apache is so old news.
- Ubuntu Lucid Lynx (10.04)
- nginx as frontend webserver
- Drupal served using fastcgi to phpcgi
- ...and Drupal's Boost module.
Most of these configs is gathered from http://groups.drupal.org/node/26363.
How fast is it now? How about almost 6,000 requests/sec, with throughput around 240Mbps? Fast enough?
