Ruby on Rails is much, much, slower than I would like. It takes around .25 seconds to render the index page: about 10 times longer than Ragnar. I've alleviated the problem somewhat by switching to a Mongrel cluster with Apache's mod-balancer, but performance is still slow. I can't add any more foreign key constraints--pretty much every feasible relationship is locked down. I guess it's just down to ActiveRecord tuning, and figuring out how to make ERB run with any semblance of speed. Possibly memcached, too...

Anyway, sorry for the inexplicable downtime. Things are still moving around quite a bit.
