Rails Best Practices

Use asset_host for production server

Use asset host for cookie-free domains for components, that make your components load faster.

Use css sprite automatically

Using css sprite can reduce a large number of http requests, so it makes the web page loaded much faster. It it painful to composite a lot of images manually, do it automatically.

Put scripts at the bottom

Do you experience that your website renders slow due to loading a lot of javascripts, especially loading some third-party javascripts? Move script tags to the bottom of body can speed up the render of your website.
