I used to run Apache bench on the code to make sure it was as 
fast as possible, for static files it is pretty performant since 
it buffers the files, and serves them directly from memory.

The main overhead comes from the external process booting up, 
rdmd is nice since it only does the compile once then reuses the 
compiled binary for external scripts. PHP and such are always hit 
with the additional overhead.

Feel free to run your own tests, the development branch has the 
latest version with some additional bug fixes not yet available 
in the master branch, and feedback is welcome and can be posted 
as an issue in Github
