...But if you are talking about a CGI script, you are _not_ talking
abouty high performance ;-)
To write a Perl program using FastCGI, you should use the FCGI module
[1]. Quoting from the man page:
use FCGI;
my $count = 0;
my $request = FCGI::Request();
while($request->Accept() >= 0) {
print("Content-type: text/html\r\n\r\n", ++$count);
}
So, basically: You need to change the way your program works, if you
are working in a traditional CGI way, so that instead of producing the
output each time the script is invoked, the setup (i.e. all needed
initialization - database connection, etc.) is performed once at the
beginning, and a request loop is created inside which each program
call is received and served.
There are several additional modules you might want to look into, such
as FCGI::Async (for asynchronous use), with slightly different
semantics, FCGI::Spawn (if you want to code closer to the bones), or
Mojo::Server::FCGI::Prefork (a preforking FastCGI implementation using
FCGI, with several simplifications).
You might be tempted to keep your old-fashioned code basically just by
replacing the CGI module for CGI::Fast - DON'T do it. CGI::Fast is not
threadable and requests will block each other.
