actually it consumes less memory than FastCGI if you do it right. If you
load as many modules and data structures as you can at startup time,
Apache will share the memory between the processes (as long as you don't
change the data).
With FastCGI this is not possible (or so I was told), so you usually end
up with using more memory.
