I've spent the last few days converting this site to run under <a href="http://www.moveabletype.org">Moveable Type</a> which is the coolest piece of CGI I've seen for a long long time. As <a href="http://www.aaronsw.com/weblog/000404" title="Aaron Swartz: Bake Don't Fry">Aaron</a> points out, MT is one of the new generation of retro tools that serve up static pages built from a database. The effects of this are fairly subtle and they're not raw performance related - it's a scheme that actually works with the underlying web server, using it for what it was designed for: serving pages as efficiently as possible. You immediately get all the benefit if the thousands of man-months spent developing the web server: caching, etags, proper Last-modif modified headers etc.
