When I installed CFML on a Raspberry Pi, top performance was really the least of my worries. I'm using ContentBox Modular CMS which allowed me to get this site up and running (via the CommandBox CLI) literally in about 30 minutes after booting a Raspberry Pi for the first time in my life.
This was incredibly easy and the site performs great for a single page page load with its in-memory H2 database. Hitting the home page locally loads in less than 200ms. Of course, ContentBox is a full-fledged CMS running on Hibernate ORM with theming support, dynamic content rendering, and modular plugins. It's not necessarily optimized for an embedded device. However, I'm still able to get about 15 requests a second to a ContentBox page which is a decent amount of traffic.
