You can improve asset speed in development. First of all, make sure that CACHING IS ON.

Open this file config/environments/development.rb

config.action_controller.perform_caching = true

Then restart your server.

Assets may compile slowly, but at least make them compile slowly only once, not every time. To ensure assets are cached, make sure caching is on.
