And on high volume sites, you can use boa to serve static contents. It's a single process web server that uses non-blocking IO. It's roughly 3 times faster than apache for static content. IIRC /. uses boa to serve static images.. There are other small web servers like roxen which are pretty fast too. Performance is apache selling point. Flexibility and verasatility is.
