It's a no-brainer, if you're worried mainly about performance. Basic story: mod_perl embeds a perl interpreter in Apache. No starting up a separate perl interpreter when you start a CGI script! Secondly, Apache::DBI allows database connection pooling, and pretty intelligently. It's a *big* speed gain, but there is increased memory usage.

If you code cleanly, and follow the guidelines you've already read, you shouldn't have much of a problem. Eventually, the thing to do is move away from thinking in terms of CGI scripts and writing mod_perl handlers; then, basically, you've got a big suite of Perl apps that groks HTTP ... mondo powerful. Why, you could even write a great website around that sort of technology! 

perl -e 'print "How sweet does a rose smell? "; chomp ($n = <STDIN>); 
+$rose = "smells sweet to degree $n"; *other_name = *rose; print "$oth
+er_name\n"'
