This is quite nice, however, if you are wanting to serve static content I no longer believe Apache the proper tool for the job. Use cherokee, lighttpd or nginx, they are all faster and have decent file interfaces.

Personally I'd just stick Varnish in front of it and keep using the webserver that I've always felt comfortable with, Apache.
