mod_perl lets you to embed Perl interpretator in Apache. FastCGI allows to run any application as a daemon which communicates with web server. Main differences (beware that I don't use FastCGI myself and run my web programms under mod_perl so I can be wrong in some details):
  1. mod_perl is highly coupled with Apache and gives your Perl applications access to its internals what impossible with FastCGI
  2. mod_perl is for Apache only. FastCGI supports other web servers as well
  3. mod_perl is for Perl only. FastCGI is not limited to Perl
  4. Since FastCGI runs your program as a separate daemon it can run under different UID/GID than web server. FastCGI may be more flexiable when it comes to dealing with security polices.
  5. Probably other things I forgot to mention or I don't know.
Personally I prefer mod_perl (mostly because of #1).
