Today is again a full $job day. Thanks to Jesse, I discovered the amazing lighttpd web server (the equivalent of SQLite of web servers), and promptly hacked Jifty::Script::FastCGI to support it. These two lines of config worked wonders on a FreeBSD setup, providing such an instaneous feedback that I simply wasn't used to:
server.event-handler = "freebsd-kqueue"
server.stat-cache-engine = "fam"
On another 350mhz AIX machine (on which I can't manage to get mod_perl2 or mod_fastcgi built), the response speed is easily twice that of Jifty's native web server, and the memory footprint is a mere 3mb. Authentication is also made much easier with the builtin FastCGI authorizer.
Much kudos to Jan Kneschke and the lighttpd team for creating this lovely lighty creature. :-)
