Yes, mod_perl is preferable, but let's not let Ronny be confused by this.
Configuration of mod_perl is separate from regular CGI.

To be more precise, there is still a perl interpreter, it's just
embedded in the Apache server process.  Each script is compiled into
memory as a perl routine.  This is only necessary on the first
execution, which is where the performance boost comes from.

Actually you do need to pay more attention to how scripts are written.
You must "use strict;" and pay close attention to scoping issues by
judicious use of "my/our/local", among other things.  If you do these
things, then yes it's possible to run scripts virtually unaltered,
thanks to Apache::Registry and friends.
