I have used a combination of the following to achieve quick CGI response
from the DB with little modification to existing CGI code:
FastCGI (http://www.fastcgi.com/) and mod_fcgi for Apache
(http://www.apache.org/)
Perl (http://www.perl.com), compiled with the sfio extensions
(http://www.perl.com/CPAN-local//src/misc/sfio97.src.unix.tar.gz)
DBI (http://www.perl.com/CPAN-local//modules/by-module/DBI/) and
appropriate DBD (http://www.perl.com/CPAN-local//modules/by-module/DBD/)
CGI.pm
(http://www.perl.com/CPAN-local//modules/by-module/CGI/)
The only drawback that I've noticed is that each script you run consumes a
fair bit of memory. Assuming you've got lots of RAM, it's *much* faster
than trying to fire up databased scripts on a per request basis. There are
other ways of doing things which may make better use of resources (like
mod_perl & DBI) but the FastCGI method can help you get around some sticky
issues when you have a bunch of existing scripts.
