The webserver is doing multiple virtual hosts with a mixture of static and dynamic content. The dynamic pages are currently a php5. I intended to add mod_python to the mix so I could put together some sites with Django but I noticed a slowdown on the webserver immediately after adding mod_python as an apache DSO and adding:
