The problem with CGI is that it involves restarting the application
for every page request. This means reloading the Lua script from disk
and performing all of the startup initialization with each request,
which can add up to a substantial amount of overhead. It also means
there's no in-memory persistence between requests, so you've got to
persist session data to disk (or at least to shared memory) and reload
it every request as well.
All of CGI's successors sidestep this problem.
