my experience with php seems to confirm this. php compilation is so fast 
that it's okay to use PHP CGI for medium traffic and simple to medium 
application complexity.

*but*, if your application needs to compile 1000+ lines of php code on 
every request (e.g. you include/require several libraries, like PEAR 
modules), the overhead does start to show itself (0.5-1 seconds or more 
of delay).

php cgi apps seems faster since most libraries are written in C, while 
Perl's (and Ruby's) are written in pure Perl/Ruby code so they need to 
compile many lines of code per request. but this situation is changing 
everyday that PEAR is more and more used everyday...
