Rails Performance Still Disappointing
Ruby on Rails remains far slower than desirable, with the index page taking roughly .25 seconds to render—about 10 times slower than Ragnar. A switch to a Mongrel cluster with Apache's mod-balancer has helped, but performance is still lacking.
Database schema optimization is no longer an option: nearly every feasible foreign key relationship is already in place. That leaves tuning ActiveRecord, figuring out how to make ERB run faster, and possibly adding memcached.
Apologies for the downtime during this period—things are still being relocated and adjusted.
