Does your server run Fast CGI? If not, there is no reason why you would use CGI::Fast
mod_fastcgi for Apache is a third-party module and can be found at www.fastcgi.com. You will also need to install the FCGI module from CPAN. Fast CGI also exists for other servers.
Much more info is to be found in the documentation.
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
