Just wanted to put up some useful methods for fine-tuning Rails performance. I’ve never tried all the methods in this list at once, but if you find your app bottlenecking in a particular area, here’s some fixes.

- cache_fu [github.com] – ActiveRecord memcached plugin
- cache-money [github.com] – Another ActiveRecord memcached plugin
- More Cache Plugins [agilewebdevelopment.com]
- AssetPacker [synthesis.sbecker.net] – Dynamically pack JS/CSS files
